The predicted results of virial coefficients from different equations of state of hard body fluids such as linearly tangent hard spheres, hard ellipsoidals or hard spherocylinders have been used to calculate the values of nonsphericity factor and the van der Waals parameters. The parameters of these equations of state testify the predicted critical properties satisfactorily. The improved accuracy of the predicted results has been observed by incorporating the chain concept with the shape of the molecules of binary mixtures of hydrocarbons.
