11 Due 4/7

1. A turbine takes in 2 kg/s neon at 27$^\circ$C and 200 kPa with negligible velocity. The produced work is 75 kW and 30 kW of heat leaks into the turbine from the surroundings. The neon exits at 100 kPa and 230 K. Find the exit velocity of the neon.

2. An adiabatic turbine receives 12kg/s of steam at 10 MPa and 450$^\circ$C at a velocity of 80 m/s. The steam exits the turbine at a pressure of 10 kPa, with a quality of 92%, at a velocity of 50 m/s. Find the kinetic energy change of the water, the produced power, and the diameter of the entrance pipe.

3. Engine coolant (glycerine) enters the radiator of your car with a temperature of 100$^\circ$C and exits it at 50$^\circ$C. If the coolant must remove 30 kW of heat, what must be its mass flow rate through the radiator? If the heat is carried off by ambient air at about one atmosphere that has a temperature of 15 degrees before flowing through the radiator and 35 degrees after it, what is the volume flow of the air?

4. Do 6.106 in the hardcover or 6.87 in the softcover.
