R134a

[bornehatred]

does anyone knows this equation (see attachment) which been derived from Martin-Hou's equation of state for R134a.
it seems that i cant get the value right even after using the values from DuPont's..can anyone help me out here?

If the derivation and coefficients are correct, then it's a math error someplace. It's been a long time since I have worked with this, but are you sure about the actual equations and coefficients from Dupont?

Sorry
were does "A" come in to the equation, I was with it until then but I lost it after that.
