WebREFPROP does not provide thermodynamic properties as a function of density and specific entropy. However REFPROP does provide specific entropy, s, as a function of temperature, T, and density, ρ. Therefore an algorithm based on a secant method3 was used to numerically solve for T given ρ and s. Progressively better estimates for Tj are found by WebApr 1, 2007 · 55 predefined mixtures (such as R407C, R410A, and air); the user may define and store others; Source code: The FORTRAN subroutines and associated fluid data files are provided for those wishing to access REFPROP calculations from their own applications.
