A steam power plant operates on a simple practical power cycle. Steam generated in a constant pressure boiler at 8,500kPa and 600C is fed to an adiabatic turbine where work is produced. Exhaust from the turbine enters the condenser at 10 kPa. Turbine and pump efficiencies are both 80%. The power rating of the plant is 70, 000k W. Show the cycle on T-S plane; and determine the steam rate, the heat-transfer rate in the boiler, and the thermal efficiency of the plant.
