During the cycle in a power plant operating by realizing the ideal reheating Rankine cycle, water vapor is produced in the boiler at 3 MPa and 600oC. The condenser is kept at 45oC by transferring 10 MW of heat to the outside. In this power plant the high pressure turbine expands to 500 kPa and then the fluid is reheated and then expanded again in the low pressure turbine. According to this; a) Calculate the reheating temperature of the fluid for the case where the low pressure turbine outlet is saturated steam. b) Calculate the total turbine power (kW) obtained from the turbines and the total heat transfer to the boiler (kW) during this cycle. c) Draw the T-s diagram of the cycle showing also the saturation curves.
