.ThermofluidStream.Media.myMedia.R134a.R134a_ph.isentropicExponent

Information

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.
