Absolute Humidity
type: QuantityKind
description: $\textit{Absolute Humidity}$ is an amount of water vapor, usually discussed per unit volume. Absolute humidity in air ranges from zero to roughly 30 grams per cubic meter when the air is saturated at $30 ^\circ C$. The absolute humidity changes as air temperature or pressure changes. $$$$ This is very inconvenient for chemical engineering calculations, e.g. for clothes dryers, where temperature can vary considerably. As a result, absolute humidity is generally defined in chemical engineering as mass of water vapor per unit mass of dry air, also known as the mass mixing ratio, which is much more rigorous for heat and mass balance calculations. $$$$ Mass of water per unit volume as in the equation above would then be defined as volumetric humidity, because of the potential confusion.

comment: Applicable units are those of quantitykind:AbsorbedDose
comment: Note that the absorbed dose is not a good indicator of the likely biological effect. 1 Gy of alpha radiation would be much more biologically damaging than 1 Gy of photon radiation for example. Appropriate weighting factors can be applied reflecting the different relative biological effects to find the equivalent dose. The risk of stoctic effects due to radiation exposure can be quantified using the effective dose, which is a weighted average of the equivalent dose to each organ depending upon its radiosensitivity. When ionising radiation is used to treat cancer, the doctor will usually prescribe the radiotherapy treatment in Gy. When risk from ionising radiation is being discussed, a related unit, the Sievert is used.

amount of substance
type: QuantityKind
description: $\textit{Amount of Substance}$ is a standards-defined quantity that measures the size of an ensemble of elementary entities, such as atoms, molecules, electrons, and other particles. It is sometimes referred to as chemical amount. The International System of Units (SI) defines the amount of substance to be proportional to the number of elementary entities present. The SI unit for amount of substance is mole. It has the unit symbol $mol$. The mole is defined as the amount of substance that contains an equal number of elementary entities as there are atoms in 0.012kg of the isotope carbon-12. This number is called Avogadro's number and has the value $6.02214179(30) \times 10^{23}$. The only other unit of amount of substance in current use is the $pound-mole$ with the symbol $lb-mol$, which is sometimes used in chemical engineering in the United States. One $pound-mole$ is exactly $453.59237 mol$.

Angular Momentum
type: QuantityKind
description: $\textit{Angular Momentum}$, $\textit{Moment of Momentum}$, or $\textit{Rotational Momentum}$, is a vector quantity that represents the product of a body's rotational inertia and rotational velocity about a particular axis. The $\textit{Angular Momentum}$ of an object rotating about some reference point is the measure of the extent to which the object will continue to rotate about that point unless acted upon by an external torque. In particular, if a point mass rotates about an axis, then the angular momentum with respect to a point on the axis is related to the mass of the object, the velocity and the distance of the mass to the axis. While the motion associated with linear momentum has no absolute frame of reference, the rotation associated with angular momentum is sometimes spoken of as being measured relative to the fixed stars.

plain text description: Angular Momentum of an object rotating about some reference point is the measure of the extent to which the object will continue to rotate about that point unless acted upon by an external torque. In particular, if a point mass rotates about an axis, then the angular momentum with respect to a point on the axis is related to the mass of the object, the velocity and the distance of the mass to the axis. While the motion associated with linear momentum has no absolute frame of reference, the rotation associated with angular momentum is sometimes spoken of as being measured relative to the fixed stars. $\textit{Angular Momentum}$, $\textit{Moment of Momentum}, or $\textit{Rotational Momentum", is a vector quantity that represents the product of a body's rotational inertia and rotational velocity about a particular axis.

Blood Glucose Level
type: QuantityKind
description: Blood sugar level, blood sugar concentration, or blood glucose level is the amount of glucose present in the blood of humans and animals. Glucose is a simple sugar and approximately 4 grams of glucose are present in the blood of humans at all times. Stored in skeletal muscle and liver cells in the form of glycogen, the body tightly regulates blood glucose levels as a part of metabolic homeostasis. During fasting blood glucose is maintained at a constant level at the expense of the glycogen stores in the liver and skeletal muscle. There are two main methods of describing concentrations: by weight, and by molecular count. Weights are in grams and molecular counts in moles. A mole is $6.022\times 10^{23}$ molecules. In both cases, the unit is usually modified by $milli-$ or $micro-$ or other prefix, and is always $per$ some volume, often a litre. Conversion factors depend on the molecular weight of the substance in question. $mmol/L$ is millimoles/liter, and is the world standard unit for measuring glucose in blood. Specifically, it is the designated SI (Systeme International) unit. Some countries use $mg/dl$. A mole is about $6\times 10^{23}$ molecules. $mg/dL$ (milligrams/deciliter) is the traditional unit for measuring $bG$ (blood glucose). There is a trend toward using $mmol/L$ however $mg/dL$ is much in practice. Some use is made of $mmol/L$ as the primary unit with $mg/dL$ quoted in parentheses. This acknowledges the large base of health care providers, researchers and patients who are already familiar with $mg/dL$.

Body Mass Index
type: QuantityKind
description: $\textit{Body Mass Index}$, BMI, is an index of weight for height, calculated as: $BMI = \frac{M_{body}}{H^2}$, where $M_{body}$ is body mass in kg, and $H$ is height in metres. The BMI has been used as a guideline for defining whether a person is overweight because it minimizes the effect of height, but it does not take into consideration other important factors, such as age and body build. The BMI has also been used as an indicator of obesity on the assumption that the higher the index, the greater the level of body fat.

Catalytic Activity
type: QuantityKind
description: An index of the actual or potential activity of a catalyst. The catalytic activity of an enzyme or an enzyme-containing preparation is defined as the property measured by the increase in the rate of conversion of a specified chemical reaction that the enzyme produces in a specified assay system. Catalytic activity is an extensive quantity and is a property of the enzyme, not of the reaction mixture; it is thus conceptually different from rate of conversion although measured by and equidimensional with it. The unit for catalytic activity is the $katal$; it may also be expressed in mol $s^{-1}$. Dimensions: $N T^{-1}$. Former terms such as catalytic ability, catalytic amount, and enzymic activity are no er recommended. Derived quantities are molar catalytic activity, specific catalytic activity, and catalytic activity concentration. Source(s): www.answers.com

Compressibility Factor
type: QuantityKind
description: The compressibility factor ($Z$) is a useful thermodynamic property for modifying the ideal gas law to account for the real gas behaviour. The closer a gas is to a phase change, the larger the deviations from ideal behavior. It is simply defined as the ratio of the molar volume of a gas to the molar volume of an ideal gas at the same temperature and pressure. Values for compressibility are calculated using equations of state (EOS), such as the virial equation and van der Waals equation. The compressibility factor for specific gases can be obtained, with out calculation, from compressibility charts. These charts are created by plotting Z as a function of pressure at constant temperature.

Curvature
type: QuantityKind
description: The canonical example of extrinsic curvature is that of a circle, which has curvature equal to the inverse of its radius everywhere. Smaller circles bend more sharply, and hence have higher curvature. The curvature of a smooth curve is defined as the curvature of its osculating circle at each point. The osculating circle of a sufficiently smooth plane curve at a given point on the curve is the circle whose center lies on the inner normal line and whose curvature is the same as that of the given curve at that point. This circle is tangent to the curve at the given point. The magnitude of curvature at points on physical curves can be measured in $diopters$ (also spelled $dioptre$) — this is the convention in optics.

Dimensionless
type: QuantityKind
description: In dimensional analysis, a dimensionless quantity or quantity of dimension one is a quantity without an associated physical dimension. It is thus a "pure" number, and as such always has a dimension of 1. Dimensionless quantities are widely used in mathematics, physics, engineering, economics, and in everyday life (such as in counting). Numerous well-known quantities, such as $\pi$, $\epsilon$, and $\psi$, are dimensionless. By contrast, non-dimensionless quantities are measured in units of length, area, time, etc. Dimensionless quantities are often defined as products or ratios of quantities that are not dimensionless, but whose dimensions cancel out when their powers are multiplied.

Dose Equivalent
type: QuantityKind
description: "Dose Equivalent" (former), or $\textit{Equivalent Absorbed Radiation Dose}$, usually shortened to $\textit{Equivalent Dose}$, is a computed average measure of the radiation absorbed by a fixed mass of biological tissue, that attempts to account for the different biological damage potential of different types of ionizing radiation. The equivalent dose to a tissue is found by multiplying the absorbed dose, in gray, by a dimensionless "quality factor" $Q$, dependent upon radiation type, and by another dimensionless factor $N$, dependent on all other pertinent factors. N depends upon the part of the body irradiated, the time and volume over which the dose was spread, even the species of the subject.

Dry Volume
type: QuantityKind
description: Dry measures are units of volume used to measure bulk commodities which are not gas or liquid.

They are also used in fishing for clams, crabs, etc. and formerly for many other substances (for example coal, cement, lime) which were typically shipped and delivered in a standardized container such as a barrel. In the original metric system, the unit of dry volume was the stere, but this is not part of the modern metric system; the liter and the cubic meter ($m^{3}$) are now used. However, the stere is still widely used for firewood.

electric charge
type: QuantityKind
description: "Electric Charge" is a fundamental conserved property of some subatomic particles, which determines their electromagnetic interaction. Electrically charged matter is influenced by, and produces, electromagnetic fields. The electric charge on a body may be positive or negative. Two positively charged bodies experience a mutual repulsive force, as do two negatively charged bodies. A positively charged body and a negatively charged body experience an attractive force. Electric charge is carried by discrete particles and can be positive or negative. The sign convention is such that the elementary electric charge $e$, that is, the charge of the proton, is positive. The SI derived unit of electric charge is the coulomb.

electric dipole moment
type: QuantityKind
description: "Electric Dipole Moment" is a measure of the separation of positive and negative electrical charges in a system of (discrete or continuous) charges. It is a vector-valued quantity. If the system of charges is neutral, that is if the sum of all charges is zero, then the dipole moment of the system is independent of the choice of a reference frame; however in a non-neutral system, such as the dipole moment of a single proton, a dependence on the choice of reference point arises. In such cases it is conventional to choose the reference point to be the center of mass of the system or the center of charge, not some arbitrary origin. This convention ensures that the dipole moment is an intrinsic property of the system. The electric dipole moment of a substance within a domain is the vector sum of electric dipole moments of all electric dipoles included in the domain.

electric polarization
type: QuantityKind
description: "Electric Polarization" is the relative shift of positive and negative electric charge in opposite directions within an insulator, or dielectric, induced by an external electric field. Polarization occurs when an electric field distorts the negative cloud of electrons around positive atomic nuclei in a direction opposite the field. This slight separation of charge makes one side of the atom somewhat positive and the opposite side somewhat negative. In some materials whose molecules are permanently polarized by chemical forces, such as water molecules, some of the polarization is caused by molecules rotating into the same alignment under the influence of the electric field. One of the measures of polarization is electric dipole moment, which equals the distance between the slightly shifted centres of positive and negative charge multiplied by the amount of one of the charges. Polarization P in its quantitative meaning is the amount of dipole moment p per unit volume V of a polarized material, P = p/V.

Energy Expenditure
type: QuantityKind
description: Energy expenditure is dependent on a person's sex, metabolic rate, body-mass composition, the thermic effects of food, and activity level. The approximate energy expenditure of a man lying in bed is $1.0\,kilo\,calorie\,per\,hour\,per\,kilogram$. For slow walking (just over two miles per hour), $3.0\,kilo\,calorie\,per\,hour\,per\,kilogram$. For fast steady running (about 10 miles per hour), $16.3\,kilo\,calorie\,per\,hour\,per\,kilogram$. Females expend about 10 per cent less energy than males of the same size doing a comparable activity. For people weighing the same, individuals with a high percentage of body fat usually expend less energy than lean people, because fat is not as metabolically active as muscle.

enthalpy
type: QuantityKind
description: In thermodynamics, $\textit{enthalpy}$ is the sum of the internal energy $U$ and the product of pressure $p$ and volume $V$ of a system. The characteristic function (also known as thermodynamic potential) $\textit{enthalpy}$ used to be called $\textit{heat content}$, which is why it is conventionally indicated by $H$. The specific enthalpy of a working mass is a property of that mass used in thermodynamics, defined as $h=u+p \cdot v$, where $u$ is the specific internal energy, $p$ is the pressure, and $v$ is specific volume. In other words, $h = H / m$ where $m$ is the mass of the system. The SI unit for $\textit{Specific Enthalpy}$ is $\textit{joules per kilogram}$

force
type: QuantityKind
description: "Force" is an influence that causes mass to accelerate. It may be experienced as a lift, a push, or a pull. Force is defined by Newton's Second Law as $F = m \times a $, where $F$ is force, $m$ is mass and $a$ is acceleration. Net force is mathematically equal to the time rate of change of the momentum of the body on which it acts. Since momentum is a vector quantity (has both a magnitude and direction), force also is a vector quantity.

frequency
type: QuantityKind
description: "Frequency" is the number of occurrences of a repeating event per unit time. The repetition of the events may be periodic (that is. the length of time between event repetitions is fixed) or aperiodic (i.e. the length of time between event repetitions varies). Therefore, we distinguish between periodic and aperiodic frequencies. In the SI system, periodic frequency is measured in hertz (Hz) or multiples of hertz, while aperiodic frequency is measured in becquerel (Bq). In spectroscopy, $\nu$ is mostly used. Light passing through different media keeps its frequency, but not its wavelength or wavenumber.

API Gravity
type: QuantityKind
description: The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water: if its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks. API gravity is thus an inverse measure of a petroleum liquid's density relative to that of water (also known as specific gravity). It is used to compare densities of petroleum liquids. For example, if one petroleum liquid is less dense than another, it has a greater API gravity. Although API gravity is mathematically a dimensionless quantity (see the formula below), it is referred to as being in 'degrees'. API gravity is graduated in degrees on a hydrometer instrument. API gravity values of most petroleum liquids fall between 10 and 70 degrees.

Heat Capacity Ratio
type: QuantityKind
description: The heat capacity ratio, or ratio of specific heats, is the ratio of the heat capacity at constant pressure ($C_P$) to heat capacity at constant volume ($C_V$). For an ideal gas, the heat capacity is constant with temperature ($\theta$). Accordingly we can express the enthalpy as $H = C_P*\theta$ and the internal energy as $U = C_V \cdot \theta$. Thus, it can also be said that the heat capacity ratio is the ratio between enthalpy and internal energy.

Heat Flow Rate
type: QuantityKind
description: The rate of heat flow between two systems is measured in watts (joules per second). The formula for rate of heat flow is $\bigtriangleup Q / \bigtriangleup t = -K \times A \times \bigtriangleup T/x$, where $\bigtriangleup Q / \bigtriangleup t$ is the rate of heat flow; $-K$ is the thermal conductivity factor; A is the surface area; $\bigtriangleup T$ is the change in temperature and $x$ is the thickness of the material. $\bigtriangleup T/ x$ is called the temperature gradient and is always negative because of the heat of flow always goes from more thermal energy to less).

Internal Energy
type: QuantityKind
description: "Internal Energy" is simply its energy. "internal" refers to the fact that some energy contributions are not considered. For instance, when the total system is in uniform motion, it has kinetic energy. This overall kinetic energy is never seen as part of the internal energy; one could call it external energy. Or, if the system is at constant non-zero height above the surface the Earth, it has constant potential energy in the gravitational field of the Earth. Gravitational energy is only taken into account when it plays a role in the phenomenon of interest, for instance in a colloidal suspension, where the gravitation influences the up- downward motion of the small particles comprising the colloid. In all other cases, gravitational energy is assumed not to contribute to the internal energy; one may call it again external energy.

kinematic viscosity
type: QuantityKind
description: The ratio of the viscosity of a liquid to its density. Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress. In many situations, we are concerned with the ratio of the inertial force to the viscous force (that is the Reynolds number), the former characterized by the fluid density $\rho$. This ratio is characterized by the kinematic viscosity (Greek letter $\nu$), defined as follows: $\nu = \mu / \rho$. The SI unit of $\nu$ is $m^{2}/s$. The SI unit of $\nu$ is $kg/m^{1}$.

Luminous Flux per Area
type: QuantityKind
description: In photometry, illuminance is the total luminous flux incident on a surface, per unit area. It is a measure of how much the incident light illuminates the surface, wavelength-weighted by the luminosity function to correlate with human brightness perception. Similarly, luminous emittance is the luminous flux per unit area emitted from a surface. In SI derived units these are measured in $lux (lx)$ or $lumens per square metre$ ($cd \cdot m^{-2}$). In the CGS system, the unit of illuminance is the $phot$, which is equal to $10,000 lux$. The $foot-candle$ is a non-metric unit of illuminance that is used in photography.

Reflectivity
type: QuantityKind
description: For homogeneous and semi-infinite materials, reflectivity is the same as reflectance. Reflectivity is the square of the magnitude of the Fresnel reflection coefficient, which is the ratio of the reflected to incident electric field; as such the reflection coefficient can be expressed as a complex number as determined by the Fresnel equations for a single layer, whereas the reflectance is always a positive real number. For layered and finite media, according to the CIE, reflectivity is distinguished from reflectance by the fact that reflectivity is a value that applies to thick reflecting objects. When reflection occurs from thin layers of material, internal reflection effects can cause the reflectance to vary with surface thickness. Reflectivity is the limit value of reflectance as the sample becomes thick; it is the intrinsic reflectance of the surface, hence irrespective of other parameters such as the reflectance of the rear surface. Another way to interpret this is that the reflectance is the fraction of electromagnetic power reflected from a specific sample, while reflectivity is a property of the material itself, which would be measured on a perfect machine if the material filled half of all space.

description: $\textit{Specific Energy}$ is defined as the energy per unit mass. Common metric units are $J/kg$. It is an intensive property. Contrast this with energy, which is an extensive property. There are two main types of specific energy: potential energy and specific kinetic energy. Others are the $\textit{gray}$ and $\textit{sievert}$, which are measures for the absorption of radiation. $$$$ The concept of specific energy applies to a particular or theoretical way of extracting useful energy from the material considered that is usually implied by context. These intensive properties are each symbolized by using the lower case letter of the symbol for the corresponding extensive property, which is symbolized by a capital letter. For example, the extensive thermodynamic property enthalpy is symbolized by $H$; specific enthalpy is symbolized by $h$.

Strain
type: QuantityKind
description: In any branch of science dealing with materials and their behaviour, strain is the geometrical expression of deformation caused by the action of stress on a physical body. Strain is calculated by first assuming a change between two body states: the beginning state and the final state. Then the difference in placement of two points in this body in those two states expresses the numerical value of strain. Strain therefore expresses itself as a change in size and/or shape.

Stress
type: QuantityKind
description: Stress is a measure of the average amount of force exerted per unit area of a surface within a deformable body on which internal forces act. In other words, it is a measure of the intensity or internal distribution of the total internal forces acting within a deformable body across imaginary surfaces. These internal forces are produced between the particles in the body as a reaction to external forces applied on the body. Stress is defined as ${\rm{Stress}} = \frac{F}{A}$.

torque
type: QuantityKind
description: In physics, a torque ($\tau$) is a vector that measures the tendency of a force to rotate an object about some axis. The magnitude of a torque is defined as force times its lever arm. Just as a force is a push or a pull, a torque can be thought of as a twist. The SI unit for torque is newton meters ($N m$). In U.S. customary units, it is measured in foot pounds (ft lbf) (also known as "pounds feet"). Mathematically, the torque on a particle (which has the position r in some reference frame) can be defined as the cross product: $τ = r x F$ where, r is the particle's position vector relative to the fulcrum F is the force acting on the particles, or, more generally, torque can be defined as the rate of change of angular momentum: $τ = dL/dt$ where, L is the angular momentum vector t stands for time.

Turbidity
type: QuantityKind
description: Turbidity is the cloudiness or haziness of a fluid, or of air, caused by individual particles (suspended solids) that are generally invisible to the naked eye, similar to smoke in air. Turbidity in open water is often caused by phytoplankton and the measurement of turbidity is a key test of water quality. The higher the turbidity, the higher the risk of the drinkers developing gastrointestinal diseases, especially for immune-compromised people, because contaminants like virus or bacteria can become attached to the suspended solid. The suspended solids interfere with water disinfection with chlorine because the particles act as shields for the virus and bacteria. Similarly suspended solids can protect bacteria from UV sterilisation of water. Fluids can contain suspended solid matter consisting of particles of many different sizes. While some suspended material will be large enough and heavy enough to settle rapidly to the bottom container if a liquid sample is left to stand (the settleable solids), very small particles will settle only very slowly or not at all if the sample is regularly agitated or the particles are colloidal. These small solid particles cause the liquid to appear turbid.

Viscosity
type: QuantityKind
description: Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or extensional stress. In general terms it is the resistance of a liquid to flow, or its "thickness". Viscosity describes a fluid's internal resistance to flow and may be thought of as a measure of fluid friction. [Wikipedia]. In general conversation or in non-scientific contexts, if someone refers to the viscosity of a fluid, they're likely talking about its dynamic (or absolute) viscosity. However, in engineering or scientific contexts, it's essential to clarify which type of viscosity is being discussed, as the interpretation and use of the data may differ depending on whether one is talking about dynamic or kinematic viscosity.

Volume Thermal Expansion
type: QuantityKind
description: When the temperature of a substance changes, the energy that is stored in the intermolecular bonds between atoms changes. When the stored energy increases, so does the length of the molecular bonds. As a result, solids typically expand in response to heating and contract on cooling; this dimensional response to temperature change is expressed by its coefficient of thermal expansion. Different coefficients of thermal expansion can be defined for a substance depending on whether the expansion is measured by: * linear thermal expansion * area thermal expansion * volumetric thermal expansion These characteristics are closely related. The volumetric thermal expansion coefficient can be defined for both liquids and solids. The linear thermal expansion can only be defined for solids, and is common in engineering applications. Some substances expand when cooled, such as freezing water, so they have negative thermal expansion coefficients. [Wikipedia]

work
type: QuantityKind
description: $\textit{Work}$ or $net\ work$ is equal to the change in kinetic energy. This relationship is called the work-energy theorem: $$Wnet = K. E._f K. E._o $$ where $K. E._f$ is the final kinetic energy and $K. E._o$ is the original kinetic energy. Potential energy, also referred to as stored energy, is the ability of a system to do work due to its position or internal structure. Change in potential energy is equal to work. The potential energy equations can also be derived from the integral form of work: $$\Delta P. E. = W = \int F \cdot dx$$.

plain text description: A force is said to do Work when it acts on a body so that there is a displacement of the point of application, however small, in the direction of the force. The concepts of work and energy are closely tied to the concept of force because an applied force can do work on an object and cause a change in energy. Energy is defined as the ability to do work. Work is done on an object when an applied force moves it through a distance. Kinetic energy is the energy of an object in motion. The net work is equal to the change in kinetic energy.

Work Function
type: QuantityKind
description: "Work Function" is the energy difference between an electron at rest at infinity and an electron at a certain energy level. The minimum energy (usually measured in electronvolts) needed to remove an electron from a solid to a point immediately outside the solid surface (or energy needed to move an electron from the Fermi level into vacuum).
