Water vapor is introduced into a turbine that operates in a steady state with a mass rate of 4600 kg/h. The turbine develops a power of 1000 kW. At the inlet, the pressure is 6100 kPa, the temperature is 400 ºC, the speed is 10 m/s. At the outlet the pressure is 10 kPa, the quality (x) is 0.90 (90%), and the speed is 50 m/s. Calculate the heat transfer rate between the turbine and the neighborhood considering the kinetic energy variation
