Homework Statement
Vapor mercury is to be adiabatically and reversibly compressed from 0.1 MPa to 10 MPa in a
continuous process. Compute the work required in Joules per mole.
Properties of Mercury
Tc =1735 K, Pc =161 MPa.
ω=-0.1644, CP/R =2.5
Homework Equations
The Peng Robinson Equation of State...(see attached file)
work=delta(H)
H=Cp*delta(T)
(Cp/R)*R= Cp
R=8.314
The Attempt at a Solution
I'm having trouble getting started. I think I need to solve PREOS for the T to find the change in T. But that can't be all because I still don't know the density. So that's one equation and twp unknown. On top of that, I have Pc, Tc rather than T and P. If I don't have Tr I can't find those.
It must be rather apparent that I need some serious help. If anyone can help get me on the right track I would appreciate it very much.
Thanks in advance.
