Abstract

The computational method for calculations of pure substances critical parameters from united equation of state is suggested. It is based on approach of critical state through inflection points of pressure as function of volume at fixed temperature. The features and main steps of calculation with help of algorithm considered. Results of critical parameters calculations from polynomial equation of state are discussed.
