The net power (NOT TURBINE POWER) of the following steam power cycle is desired to be 25MW.Steam enters the turbine at 16 MPa, 450C, condenser at 10kPa pressure saturated liquid-steamIt enters as a mixture. Compressed liquid enters the pump at 9kPa at 35C and at 17MPacomes out. The inlet pressure to the boiler is 16.8MPa and 33C. The output from the boiler is 16.2MPa and 575C.The isentropic efficiency of the turbine is 90%, and that of the pump is 83%. Find the mass flow rate that will provide the required net power.
Compare the thermal efficiency and turbine-exit quality (temperature if superheated) at the condenser pressure for a simple Rankine cycle and the reheat cycle when the boiler pressure is 5 MPa, the boiler exit temperature is 500°C, and the condenser pressure is 20 kPa. The reheat takes place at 0.5 MPa and the steam leaves the reheater at 500°C. (Enthalpies are in KJ/kg.) Without the reheater, the heat added is: The enthalpy entering the condenser is: The net Work is: The enthalpy entering the reheater is: Without the reheater, the net Work is:

The following is how a reheat turbine works. It takes steam with a pressure of 1560 psi and a temperature of 780 F and expands it to 430 psi. The steam now returns to the boiler to be resuperheated before returning to the turbine at 410 psi and 600 F. The steam then expands to the condenser temperature of 96 F. Calculate the efficiency of the cycle.
