Helmholtz Free Energy Eq of State for R134a
Hi guys,
i already got the equation of state for R134a. However, i do not know how to calculate enthalpy and entropy using it. I'm not a very fond student of math though. So, can anyone please show me some sample using the equation?i attached the equation since i don't know how to post it here with all those symbols and stuff.please anyone, i really need this A.S.A.P

Try at Du Pont Web site for R - 134 A thermodinamic properties, I found a chart where all that coeficients on the Ecuation of state are used,dont be afraid is just a sumatory.
Luck!
