Reference State 

    h = 0 kJ/kg, s = 0 kJ/kg-K at the boiling point of saturated liquid 

    The reference state can be changed using the $Reference directive.


Range of applicability for equation of state:

   179.7K < T < 550 K

0 < P < 250 MPa


Transport properties are provided using correlations given in:
