Air at a mass flow rate of 2 kg/s enters a turbine at 0.5 MPa and 1200 K and with a velocity of 20 m/s. It is expanded in the turbine to a pressure of 0.1 MPa and temperature 800 K. The velocity at the exit of the turbine is 80 m/s. Heat loss to the surroundings is 50 kW. The power output of the turbine in kW is 200 a) 846 c) 617 (b) 746 (d) 517 Air at a mass flow rate of 2 kg/s enters a turbine at 0.5 MPa and 1200 K and with a velocity of 20 m/s.
