virial equation of state

Chemical Engineering

A power-series expansion of the compressibility for a substance expressed in terms of molar density:
$Z = 1 + B ρ + C ρ^{2} + D ρ^{3} + …$

The equation assumes that the compressibility is unity for zero density. The coefficients B, C, and D are known as the second, third, and fourth virial coefficients, and are functions of temperature. It is used to fit experimental PVT data of compressed real gases. The equation was originally known as the Kammerlingh–Onnes equation.
