A steam power plant operates on a cycle, using a turbine that receives steam at P2=10,000kPa and T2=600oC and expands it to P3=10kPa. The expanded steam goes into a condenser that produces saturated liquid water, which is then fed in a pump to produce the compressed water. The high pressure water goes into the boiler to produce high pressure steam. The power plant in shown below. The thermodynamic efficiency of the turbine and the pump is 0.8 and the power rating of the plant is 1000,000kW. Determine the following: a) the power production of the turbine and the power requirement of the pump (kJ/kg), b) the heat transfer in the boiler and the condenser (kJ/kg), c) the steam rate (kg/sec) d) the thermal efficiency of the Rankine cycle and the actual practical power plant.
