Abstract

In this paper the approximate formulae for calculation of saturation pressure - p and ρ', ρ", h', h", s', s" as a function of saturation temperature are found. In similar manner the approximate formulae for calculation of t, ρ', ρ", h', h", s', s" as a function of p are derived. The computer subroutine in Fortran IV for all above-mentioned thermodynamic functions and parameters was written. The operating range of this subroutine is in the ranges t ∈ <-70°C; 105°С> and p ∈ <0,01223 MPa; 3,649 MPa).
