​Using the same data as problem 8.16 create a plot of the net power and thermal efficiency of the cycle as a function of pump efficiency (use EXCEL or similar program). Create an identical plot for the turbine efficiency. Vary the efficiencies from 1 to 100 % in steps of n%.
8.16 Superheated steam at 8 MPa and 480°C leaves the steam generator of a vapor power plant. Heat transfer and frictional effects in the line connecting the steam generator and the tur- bine reduce the pressure and temperature at the turbine inlet to 7.6 MPa and 440°C, respectively. The pressure at the exit of the turbine is 10 kPa, and the turbine operates adiabatically. Liquid leaves the condenser at 8 kPa, 36°C. The pressure is in- creased to 8.6 MPa across the pump. The turbine and pump isentropic efficiencies are 88%. The mass flow rate of steam is 79.53 kg/s. Determine
