JouleThomsonCoef
The JouleThomsonCoeffunction returns the Joule-Thomson coefficient of a fluid, which is defined as:
For an ideal gas, the Joule-Thomson coefficient is 0.
For a real fluid, the Joule-Thomson coefficient can be positive or negative. Positive values result in a reduction of the temperature when the pressure is reduced.
Example:
$UnitSystem SI K kPa kJ mass
T=370 [K]
P=3500 [kPa]
$VarInfo JT units=K/kPa
JT=JouleThomsonCoef(Propane,T=T,P=P)
{Solution:
JT=0.01434 [K/kPa]
}
