What are the units of Z, B, C, and D?
Homework Answers
The virtual equation of state is: pVm/RT = 1 + B/Vm + C/Vm2 + D/Vm3 + .......
where B,C,D are functions of temperature. So the units of B,C,D will be oC or oF
In the given equation Z = pV/RT. The general equation is pV = nRT i.e n= pV/RT where p is pressure,V is volume,R is gas constant, T is temperature and n is number of moles. In the given equation, n is represented as Z
Therefore, unit of Z is mole.

1. It has been claimed that the equation of state: Z = 1 + (BP/RT) can be expressed in a V-explicit as well as in a P-explicit form. If so, similar to the ideal gas equation of state PV = RT, one should be able to compute residual properties (e.g. GR, HR, SR) using two different types of integrals and both approaches should lead to the same expression for the computed residual property. Test whether this claim is true for...
