dcterms: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 \(\textit{joules per kilogram}\) |
