Homework Statement
Find the fugacity from the virial equation of state, where B is a constant.
Homework Equations
[itex]
Z=\frac{PV}{RT}=1+\frac{B}{V}
[/itex]
Don't know how to do underbars in TeX, but the V terms are on a per-mol basis. B is a constant and no further expansions of the EOS are needed. We'll be calculating this at some constant temperature T and at a discrete pressure P.
The Attempt at a Solution
Omitting the derivation of fugacity,
[itex]
f=P*exp(\frac{1}{RT}\int^{0}_{P}{V-\frac{RT}{P}dp})
[/itex]
But solving the VEOS explicitly for V, to substitute into fugacity, isn't going to work. Solving for P doesn't seem like it would be helpful. I'm presently trying to figure out how to do this with an iterative method, but the integral is throwing me off.
Any insights?
Thanks!
