Abstract

An automated system for calculating the thermodynamic properties of air, nitrogen, oxygen, and argon has been created. It allows the calculation of the density, enthalpy, entropy, isochoric and isobaric specific heats, speed of sound, viscosity, thermal conductivity and some other properties. These values 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 2500 K and at pressures up to 100 MPa for nine combinations of independent variables. The modules for calculating properties of substances that are included into system can be also included into the programs intended for the decision of applied tasks.
