Dear Dr. Koppany,

I am very interested in your paper entitled “Prediction of Petroleum Fraction Enthalpies from the Second Modification (Alpha-Version) of the van der Waals Equation” . I have one questions about this paper:

1. In Figure 2, how to calculate ideal gas enthalpy by using Lee-kesler (1976) method?

Could you please show me how to calculate ideal gas enthalpy by using one data?
