Ideal gas air medium model
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
An example for using ideal gas properties and how to compute isentropic enthalpy changes. The function that is implemented is approximate, but usually very good: the second medium record medium2 is given to compare the approximation.
