Steam enters a two stage steady state turbine at 8 MPa and 500 C. It expands in the first stage to a state of 2 MPa and 350°C. Steam is then reheated at constant pressure to a temperature of 500°C before it enters the second stage, where it exits at 30 kPa and a quality of 98%. The net power output of the turbine is 3 MW Assume the surroundings to be at...
