Abstract

A function type computer program package for “PROPATH Ver. 7.1” written by FORTRAN77 has been developed. It contains functions for helium-4, neon, argon, krypton, xenon, n-hydrogen, chlorine, nitrogen, oxygen, air, carbon dioxide, water based on the IFC 1967 formulation for industrial use, water based on the IAPS 1984 formulation for scientific and general use, ammonia, methane, ethylene, ethane, propylene, propane, refrigerants 12, 13B1, 22, 114 and 502. Some ninety functions for thermophysical properties are provided though the number of functions available for each substance differs from a substance to another. These properties are saturation pressure, saturation temperature, specific volume, specific enthalpy, specific entropy, specific internal energy, latent heat, dryness fraction, isobaric specific heat, isochoric specific heat, thermal conductivity, viscosity, surface tension, adiabatic exponent, sonic velocity and so on.
The newly developed version, PROPATH 7.1, is going to be sold as MS-FORTRAN libraries. However it may also be transferred to computer centers of any non-profit organizations free of charge.
