Compressibility factors for gases

This is a sample of the Compressibility Factor calculator. To access the working calculator, please sign up for free membership trial.

The application presented here can be used to calculate the compressibility factor or z factor of a gas, at given conditions of temperature and pressure. Pitzer correlations are used to find out the compressibility factor as a function of reduced temperature and reduced pressure. To find out the reduced properties of a gas, its critical properties must be known first.

Critical pressure of gas (Pc) = bara
Critical temperature of gas (Tc) = K
Absolute pressure of gas (P) = bara
Temperature of gas (T) = K
Compressibility factor z =
