| Abstract: | In this paper a new equation of state for fluids has been obtained by the derivation based on the theory of statistical mechanics. A gas form of the new equation has been presented and the gas parameters have been generalized. When the gas equations are used to calculate PVT properties of gases, the confident levels at which the deviations are less than 3% for pressure and less than 5% for dencity are greater than 91%. When they are used to calculate fugacity coefficients of pure gases, the confident levels at which the deviations are less than 5% are greater than 97%. |
