Mechanical Engineering

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