Unit of Heat of Vaporization — Lesson 1

The heat of vaporization is usually given in J/kg. The other SI-derived unit is in joule per mole or joule per kilomol (kmol or kgmol), which is used by Fluent software. How can I convert my input so that it might be used in Fluent software?

In Fluent software, the dimension of the molecular weight is expressed in kg/kmol (kg/kgmol = kg per 1,000 moles).

To get the correct input of heat of vaporization or the standard state enthalpy of a particular fluid at a reference temperature for Fluent software, the conversion below is required:

Standard state enthalpy in [J/kg]* Molar Mass [kg/kgmol] = Latent Heat in [J/kgmol]
