system.thermo.if97.isentropicExponent

Calculates isentropic exponent.

Syntax

system.thermo.if97.isentropicExponent(h, s) # Enthalpy and Entropy
system.thermo.if97.isentropicExponent(p, h) # Pressure and Enthalpy
system.thermo.if97.isentropicExponent(p, s) # Pressure and Entropy
system.thermo.if97.isentropicExponent(p, t) # Pressure and Temperature

info

This function must be called with named parameters.

Parameters
