Calculate IAPWS R7-97 steam condenser power from temperature, pressure and mass flow rate.
The condenser power is calculated from the change of enthalpy between the inlet steam, and the outlet water. The enthalpy change is negative for a condenser. The condenser pressure is assumed constant.
Note : There is an anomaly in the steam calculation for region 3 between the saturated vapour line, the region 2/3 boundary, and the critical pressure. Refer to the region 3 anomaly help page for more details (click the utility button on the data bar). IAPWS R7-97 is intended for industrial use, and is a simplified version of IAPWS R6-95 for scientific use. IAPWS R7-97 was developed as an improvement of the IFC-67 model.
