V_Crit
V_Crit is a function that returns the critical specific volume of the specified fluid. The returned value depends on the unit setting made in the Unit System dialog. The fluid may be a fluid name or a string variable.
Example:
$UnitSystem SI K kPa mass
$VarInfo vc units=m^3/kg
vc=V_crit(R134a) "returns the critical volume of R134a"
{Solution:
vc=0.001969 [m^3/kg]
}
