3. Steam enters a turbine operating at steady state at 30 bar and 500°C with a velocity of 80 m/s.Saturate vapor exits at 0.15 MPa and a velocity of 40 m/s. The elevation of the inlet is 4 meter higher than at the exit. The mass flow rate of the steam is 11 kg/s, and the power developed is 8 MW. (20 points) a) Determine the area at the inlet, in m?. b) The rate of heat transfer between the turbine and its surroundings, in KW.
