Consider a steam power plant operating on a simple ideal Rankine cycle and having a net power output of 57 MW. The steam enters the turbine at 9 MPa and 575 ° C and exits at 150 ° C, then it is cooled in the condenser to a pressure of 100 kPa by means of the cooling water from a lake and that circulates through the condenser tubes to a rate of 1370 kg / s. Consider leaving the pump at 120 ° C. Show the cycle on a Ts diagram with respect to the saturation lines, as well as the real and isentropic working lines of the turbine and the pump, determine a) the cycle efficiency, b) the isentropic efficiency of the turbine, c) the isentropic efficiency of the pump and d) the mass flow of the steam.
