1. Steam enters a turbine operating at steady state with a mass flow rate of 4600 kg/h. The turbine develops a power output of 1 MW. At the inlet, the pressure is 6000 kPa, the temperature is 400oC, and the velocity is 10 m/s. At the exit, the pressure is 10 kPa, the quality is 0.9 (90%), and the velocity is 30 m/s. Calculate the rate of heat transfer between the turbine and surroundings

3. Oil(light) enters a heat exchanger at 450 K with a mass flow rate of 10 kg/s and exits at 350 K. A separate stream of liquid water enters at 20oC, 500 kPa. Each stream experiences no significant change in pressure. Stray heat transfer with the surroundings of the heat exchanger and kinetic and potential energy effects can be ignored. If no water vapor is to be present in the exiting water stream, what is the minimum mass flow rate for the water?
