PLEASE SHOW ALL TABLES USED!!!!! AND HAVE NEAT HANDWRITING!! A steam generator discharges water vapor at 10 MPa and 640 degrees Celsius. The first turbine stage expands the vapor to 2 MPa, which is extracted to a feedwater heater. The remaining portion expands through the second turbine stage to a condenser pressure of 10 kPa. The heat transfer into the steam generator is 5 MW, and the first pump operates at 60% isentropic efficiency. The enthalpies exiting the feedwater heater...
