Abstract

A system for calculating the thermophysical properties of monatomic and diatomic gases, air, carbon dioxide, ammonia, some hydrocarbons and refrigerants has been created. It allows the calculation of compressibility factor, density, entropy, enthalpy, isochoric and isobaric specific heats, speed of sound, Joule-Thomson coefficient, viscosity, thermal conductivity, and some other properties. These properties can be determined in the single-phase and two-phase regions and on the phase-equilibrium lines at temperatures from the triple point up to 400-1500 K and at pressures up to 70 or 100 MPa for the one of ten combinations of independent variables: T, r; T, v; T, p; T, s; T, x; p, r; p, v; p, s; p, h; p, x.
