In a steam power plant, dry saturated steam enters the turbine at a pressure of 40 bar and exits the turbine at a pressure of 0.1 bar. The turbine has an isentropic efficiency of 90 %, and the condensate pump has an isentropic efficiency of 85 %. The water/steam mass flow rate through the plant is 200 kg/s, and all changes in kinetic and potential energy are negligible. Using this information, determine: a) The power output of the turbine, in MW. b) The power required by the pump, in MW.

Steam enters the turbine of a simple vapor power plant with a pressure of 10 MPa and temperature of 580°C and expands adiabatically to 6 kPa. Determine (a) temperature at the turbine exit. Also calculate the (b) work input in the pump (in kJ/kg) and the (c) cycle thermal efficiency, in %. Use g = 9.81 m/s2 or 32.2 ft/s2 , T(K)=T(°C)+273 and T(R)=T(°F)+460, where applicable.

4. Steam enters the condenser of a steam power plant at 20000 kPa and a quality of 95 percent with a mass flow rate of 20 Mg/h. It is to be cooled by water from a nearby river in circulating the water through the tubes within the condenser. To prevent thermal pollution, the river water is not allowed to experience a temperature rise above 10°C. If the steam is to leave the condenser as saturated liquid at 20000 Pa, determine the mass flow rate of the cooling water required.
