(OP)
Hi all. I am looking for some formulas to calculate the Cv, Cp, Heat Capacity(kJ/kG-C),Molar Volume,... with multicomponent in Hysys.
Please help me....

Thank you... I try to find some formulas to calculate in Hysys because I dont know why does it calculte like that?
RE: Calculation Formulas in Hysys
You can also look in the Hysys thermodynamics file and find the basics there - see section 2 and addendum A in https://www.ualberta.ca/CMENG/che312/F06ChE416/Hys...
For any queries, you can always contact ApsenTech support team.

Thank so much.Does it difficult to calculate by hand, I mean by hand calculator? Because I think that It is so complex.
Thanks

These values are definitely easy to be computed by a pocket calculator or (even better) in Excel spreadsheet.

I am a student,I study Hysys by myself, so I am looking for a formula to calculate a steam : Componetn: CH4(100%), Temperature = 500k, Pressure= 10 atm, Molar Flow =100 kgmole/h,PR Equation Of State...How can I calculate all of the others remain paraments (Cv, Cp, Heat Capacity(kJ/kG-C),Molar Volume)..? Help me!!!
Thank you

Theres the EOS (or in this case a selection of EOS's and then theres the flash engine, a solver that findes the equilibrium of a given mixture of components (that must be defined) at a given pressure and temperatur (or another set of defined values that makes it possible to solve for the missing).
You can replicate the calculation by hand and most college text book omn the subject (e.g. Smith and Van Ness Introduction to Chemical Engineering Thermodynamics, 7th Edition 7th Edition should be a good introduction to the subject. If you can self study this book i wont comment on but it takes some knowledge of chemistry and math up front).
