specificInternalEnergy_pTX

Return specific internal energy of moist air as a function of pressure p, temperature T and composition X

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Specific internal energy is determined from pressure p, temperature T and composition X, assuming that the liquid or solid water volume is negligible.
