isentropicExponentIsentropic exponent gamma w.r.t. thermodynamic state | not defined in two-phase region | use setState_phX function for input |
 |
Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This function calculates the isentropic exponent of R134a from the state record (e.g., use setState_phX function for input). The isentropic exponent is modelled by the fundamental equation of state of Tillner-Roth and Baehr (1994).
Restrictions
This property is only defined in one-phase region.
