The paper presents a calculation method for parameters of one-dimensional flow of real gases. The state equation for these gasas has the form p = p(T, v). For real gasas, method of calculation of the thermodynamic functions: specific heat, entropy, enthalpy and sound velocity are presented. The steady and unsteady one-dimensional isentropic flows are analysed. Theoretical part of the paper is illustrated by calculations, in which the Readlich-Kwong equation of state was used. Finnaly, the physical limitation of the method presented are discussed.
