Reference Specific Enthalpy and Entropy
I am making a comparison between the preloaded data in CFX and properties available for real fluid.
I am checking in particular the reference specific enthalpy and entropy of water at 25°C.
Ref Spec Enthalpy = -1.586E+7 J/Kg (how is it possible to have a negative value???)
Ref Spec Entropy = 2.82E+3 J/Kg/K
but looking at the values in NIST RefProp I see:
Enthalpy = 104.83 J/Kg
Entropy = 0.367 J/Kg/K
Why the values are not matching? Am I comparing different quantities? How is it possible to have a a negative Ref Spec Enthalpy in CFX?
Thanks in advance.
