Thanks @kemattil, looks good but can the prefix "CRITICAL" be avoided? if so we can reuse CUBA.TEMPERATURE etc.

[kemattil]

No, e.g. REDUCED_TEMPERATURE = (ACTUAL_)TEMPERATURE/CRITICAL_TEMPERATURE. That is,
there are three distinct temperature variables. The same for other variables ...

[ahashibon]

VAN_DER_WAALS, REDLICH_KWONG, SOAVE, PENG_ROBINSON, CARNAHAN_STARLING, --> parent should be CUBA.EQUATION_OF_STATE

[kemattil]

Yes, you are right. My mistake ...
