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).}, issn = {2083-4195}, pages = {43--54}, url = {https://papers.itc.pw.edu.pl/index.php/JPT/article/view/187} }
