s_pTX

Return specific entropy of moist air as a function of pressure p, temperature T and composition X (only valid for phi<1)

Information

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

Specific entropy of moist air is computed from pressure, temperature and composition with X[1] as the total water mass fraction.
