A steam power plant operates on an ideal Rankine cycle with two stages of reheat and has a net power output of 75 MW. Steam enters all three stages of the turbine at 550°C. The maximum pressure in the cycle is 10 MPa, and the minimum pressure is 30 kPa. Steam is reheated at 4 MPa the first time and at 2 MPa the second time.
Show the cycle on a T-s diagram with respect to the saturation lines, and determine (a) the thermal efficiency of the cycle, and (b) the mass flow rate of the steam.
