A steam turbine cycle running on a Rankin cycle between the condenser pressure of 10 kPa and the boiler pressure of 165 bar, the steam enters the high pressure turbine at a temperature of 600 ° C. The average turbine expands to 800 kPa and then enters the boiler again to be reheated to 550 ° C. The steam leaves the boiler to a low pressure turbine, where it expands to the condenser pressure. If the expansion and compression in the turbine and the pump is isotropic, and the addition of heat is constant pressure, find the efficiency of the cycle. Note point # 1 at the exit area of ​​the steam from the boiler
