Water enters one stream of an unmixed stream heat exchanger at 20°C and increases in temperature by 10°C. Air enters the second stream on the heat exchanger at 400°C and 5 kg/s. The air temperature at the exit of the heat exchanger is 200°C cooler than at the inlet. There inlet pressure of either stream is 110 kPa and is no change in pressure from inlet to exit of either stream.

a. In which region of the phase diagram is water as it enters the heat exchanger?

b. In which region of the phase diagram is water as it leaves the heat exchanger?

c. What is the change in specific internal energy of the water from the inlet to the exit?

d. Determine the flow rate of water.

e. Determine the rate of energy transfer from the air to the water.
