IsentropicExponent

The IsentropicExponent function returns the isentropic exponent of the fluid, defined by

For an ideal gas, the isentropic exponent is identical to the ratio of Cp/Cv.

Example:

$UnitSystem SI K kPa mass

T=870 [K]

P=35000 [kPa]

k_s=isentropicexponent(Steam,T=T,P=P)

r=cp(Steam_IAPWS,T=T,P=P)/cv(Steam,T=T,P=P)

{Solution:

k_s=1.331 

r=1.615 

}
