Nist Refprop 9 New!

Version 9 utilizes state-of-the-art equations of state (EOS), primarily based on the Helmholtz energy functional form. It also implements the Modified Benedict-Webb-Rubin (MBWR) EOS and Extended Corresponding States (ECS) models for fluids with limited experimental data.

This article provides a deep dive into NIST REFPROP 9: what it is, the revolutionary features it introduced, the fluids it covers, how it compares to competitors, and why engineers still rely on it today. nist refprop 9
