A steam power plant produces steam from a superheated boiler at 600 kPa and 625°C. The turbine has an isentropic efficiency of 95%. The pump is 95% efficient and the condenser operates at 3 kPa. The furnace temperature is 1100°C and the waste heat is transferred to the atmosphere, which is at 22°C. a) Calculate the cycle efficiency. b) What is the second law efficiency of the cycle? Why is it less than 1? A steam power plant produces steam from a superheated boiler at 600 kPa and 625°C. The turbine has an isentropic efficiency of 95%.
