Working with non-ideal gases

Article Abstract:

Compressibility of a non-ideal gas is the relation between pressure, volume and temperature. Various methods have been proposed to model this relationship. Two simple and proven methods for predicting the gas compressibility factor have been studied upon. One is based on generalized compressibility charts and the second is derived from the Redlich - Kwong equation.
