A somewhat simplified flow diagram for a nuclear power plant . Mass flow rates and the various states in the cycle are shown in the accompanying table. The cycle includes a number of heaters in which heat is transferred from steam, taken out of the turbine at some intermediate pressure, to liquid water pumped from the condenser on its way to the steam drum. The heat exchanger in the reactor supplies 157 MW, and it may be assumed that there is no heat transfer in the turbines.
a. Determine the temperature of the water leaving the intermediate pressure heater, T13, assuming no heat transfer to the surroundings.
b. Determine the pump work, between states 13 and 16.
