Refprop enthalpy

Web13. apr 2024 · In REFPROP, the residual entropy is calculated using the Helmholtz energy equation of state, which is based on the Helmholtz free energy of the substance. The Helmholtz free energy is a ... WebDocumentation for all high-level functions exposed. All the wrappers wrap this function in exactly the same way. For pure and pseudo-pure fluids, two state variables are required to fix the state. The equations of state are based on T and ρ as state variables, so T, ρ will always be the fastest inputs.
