value()

overridevirtual

Returns

The water vapour saturation enthalpy in region4 curve.

According to the IAPWS-IF97: http://www.iapws.org/relguide/IF97-Rev.pdf, the vapor-liquid saturation line only covers the pressure range between 611.213 Pa and 22.064 MPa. Thus, for the vapour saturation enthalpy calculated from the saturation temperature, it has the same pressure boundaries.

< reference temperature in K.

< reference pressure in Pa.
