## REFPROP Validation Data¶

Note

This figure compares the results generated from CoolProp and those generated from REFPROP. They are all results obtained in the form $$Y(T,\rho)$$, where $$Y$$ is the parameter of interest and which for all EOS is a direct evaluation of the EOS

## Consistency Plots¶

The following figure shows all the flash routines that are available for this fluid. A red + is a failure of the flash routine, a black dot is a success. Hopefully you will only see black dots. The red curve is the maximum temperature curve, and the blue curve is the melting line if one is available for the fluid.

In this figure, we start off with a state point given by T,P and then we calculate each of the other possible output pairs in turn, and then try to re-calculate T,P from the new input pair. If we don’t arrive back at the original T,P values, there is a problem in the flash routine in CoolProp. For more information on how these figures were generated, see CoolProp.Plots.ConsistencyPlots
