Nist Refprop 9 [better] Today

For mixtures, REFPROP uses models such as the and the GERG-2008 equation of state , enabling high-accuracy predictions for multi-component systems.

Mastering NIST REFPROP 9: The Industry Standard for Fluid Properties

Supports integration with Excel, Fortran DLLs, C++, MATLAB, and Python, making it versatile for automation.

The data underlying these models was not simply collected; it was meticulously culled from thousands of experimental measurements, some dating back to the 1800s, and critically assessed to create the most accurate representation possible. Even with this high standard, some correlations, such as those for ammonia, deuterium, ethanol, and neon, were identified in later literature as having room for improvement relative to other data sources. nist refprop 9

The accuracy of REFPROP 9 makes it invaluable in sectors where precise thermodynamic data is necessary for system performance optimization and safety.

Density, pressure, temperature, enthalpy, entropy, internal energy, and specific heat capacity. Transport Properties: Viscosity and thermal conductivity.
