P_SUBLIMATION

P_SUBLIMATION

P_SUBLIMATION [Pa, kPa, bar, MPa, psia, atm] returns the sublimation pressure of a specified pure substance at the specified temperature. The units and return value of this function depend on the settings in the Unit System dialog. This function accepts only one argument, in addition to the fluid name, and that is the temperature. The T= must precede the value, variable, or expression providing the temperature. The temperature must be provided in the units specified in the Unit Information dialog. The fluid may be a fluid name or a string variable.

Example:

$UnitSystem SI C kPa

PS=p_sublimation(CarbonDioxide, T=-78.5 [C])

{Solution:

PS=101 [kPa]

}

This function is implemented for selected pure fluids. Clicking P_sublimation in the list of Thermophysical properties in the Function Information dialog will identify the fluids that provide this capability.
