      In ANSYS Fluent the dimension of the molecular weight is expressed in kg/kmol (kg/kgmol = kg per 1000 moles). So to get the correct input of heat of vaporization or in general the standard state enthalpy of particular fluid at a reference temperature for Fluent the conversion below is required: standard state enthalpy in [J/kg]* Molar Mass [kg/kgmol] = Latent Heat in [J/kgmol ] Keywords: Latent Heat, kg/kmol, molecular weight
