Fugacity Coefficient of the Virial Equation Leiden Form

Fugacity Coefficient of the Virial Equation (Leiden Form) 

The relationship for the fugacity coefficient of a component in mixtures is given according to Eq. (4.64)  

If the virial equation in the Leiden form is truncated after the second term, we get according to Eq. (2.88)  

Fugadty Coefficient of the Virlal Equation (Berlin Form) 

The Berlin form of the virial equation, cut after the first term, is given by 2 = 1 + B (T) P
