Brief

Real Gas is a gas whose molecules occupy space and have interactions [1].

Real Gas deviates from Ideal Gas by proportionality term z, which is gas compressibility factor.

Equation Of State

The Real Gas EOS:

 PV = zn RT =  z\frac{m}{M} RT

Nomenclature

 m = mass, lbm
 M = molecular weight, lbm/lbmol
 n = number of moles, lbmol
 P = Pressure, psia
 R = universal gas constant, 10.7316 psia ft3/ lbmol/ °R
 T = temperature, °R
 V = volume, ft3
 z = gas compressibility factor, dimensionless
