Specify pressure or temperature and calculate the corresponding properties of saturated steam.
Basis: IAPWS-97 equations.
Range of validity:
611.213 Pa <= P <= 22.064 MPa
273.15 K <= T <= 647.096 K [The IAPWS
equations for liquid Region 1 are applicable only to 623.15K. However, these
equations are reasonably accurate near the saturation line between 623.15K
Thermodynamically, the change in Gibbs Free energy from liquid to vapor at saturation
As can be seen when running this calculation, the calculated change has an absolute
value less than 0.2 kJ/kg,
which is a permitted inconsistency corresponding to the Prague values.
