Steam enters a turbine operating at steady state at 2 MPa, 344 C with a velocity of 66 m/s. Saturated vapor exits at 0.1 MPa and a velocity of 28 m/s. The elevation of the inlet is 1 m higher than at the exit. The mass flow rate of the steam is 11 kg/s, and the power developed is 7 MW. Let g = 9.81 m/s. Determine the rate of heat transfer between the turbine and its surroundings, in kW. Steam enters a turbine operating at steady state at 2 MPa, 344 C with a velocity of 66 m/s.
