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.

The Real Gas EOS:

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

m

= mass, lb_m

M

= molecular weight, lb_m/lb_mol

n

= number of moles, lb_mol

P

= Pressure, psia

R

= universal gas constant, 10.7316 psia ft³/ lb_mol/ °R

T

= temperature, °R

V

= volume, ft³

z

= gas compressibility factor, dimensionless
