2) A power plant operating under the Rankine cycle uses a boiler to produce superheated steam at 4500kPa and 600C. The steam is fed to a turbine and exits at 25kPa. After passing through the condenser, a saturated liquid enters the pump and is pressurized to 4500kPa. If the pump and turbine efficiencies are 75% and the mass flow rate of steam is 100kg/s, determine the power output and the thermal efficiency
