Gas Compressibility Factor From The Cubic Equation

Calculate gas compressibility factor or Z factor from the cubic equation (Poling).

The compressibility factor is used to account for the non ideal behaviour of real gases. The non ideal gas law is expressed as

`P V = Z Ro T `

where :

P = gas pressure
T = gas temperature
V = gas mole volume
Z = gas compressibility factor
Ro = universal gas constant

The compressibility factor can be calculated using either the Peng Robinson, Soave, Redlich Kwong or Van Der Waals cubic equations of state (EOS). The gas data is taken from Poling.

CALCULATOR : Gas Compressibility Factor And Density From Cubic Equation Of State [FREE]   ±

Calculate gas molar volume, compressibility factor Z and density from the fluid pressure, temperature and critical point constants for selected gases.

The compressibility factor can be calculated from either the Peng Robinson, Soave, Redlich Kwong, or van der Waals equation of state (EOS). The compressibility factor calculation is valid for gas phase only. Use the Result Plot option to plot compressibility factor versus pressure and temperature, compressibility factor versus pressure and equation of state type, or compressibility factor versus temperature and equation of state type.
