The boiler of the steam power plant generates superheated steam. The pressure of the superheated steam p, is 10 MPa and temperature T, is 590 "C. Steam is expanded through turbine to condenser pressure p, of 8 kPa. The pressure of the bleed steam py is0.9 MPa. The isentropic efficiency of the turbine n, is 83 %. The mass flow rate of steam q, is 100 kg/s. After condenser, the working fluid is saturated water. The boiler efficiency is 82.0% and pump efficiency is 82.0%.
