Nist Refprop 9l
Lynelle Staudt
The mini-REFPROP program is a free sample version of the full REFPROP program(located at www.nist.gov/srd/refprop) and is meant for use as a teaching tool inthe introduction of thermodynamics to students. It contains a limited number ofpure fluids (water, CO2, R134a, nitrogen, oxygen, methane, propane, helium,hydrogen, and dodecane), along with air as a pseudo-pure fluid. It also allowsmixture calculations of a 50/50 molar mix of nitrogen and methane or of a 79/21molar mix of nitrogen and oxygen for teaching vapor-liquid equilibrium (VLE).Please note carefully that the 79/21 N2/O2 mixture is not meant for aircalculations, but as a teaching tool to study composition changes as the mixturepasses through the two phase. For actual air properties, please selectSubstance/Pseudo-Pure Fluid/Air when running the GUI.
