| Abstract: | An equation for determining the difference between the compressibility factors of saturated vapor and liquid (ZV - ZL) through cubic equations of state has been developed as a function of reduced vapor pressure Pr, reduced temperature Tr and the critical cohesion parameter Ωac of the chosen equation. The regressed equation has been presented in a polynomial expression of (Pr/Tr) and Ωac for simple non-iterative calculations. |
