Water is heated by air in a heat exchanger. The water enters at 420 K and 0.3
Question:
Water is heated by air in a heat exchanger. The water enters at 420 K and 0.3 MPa and leaves at 560 K and 0.3 MPa. The mass flow rate of the water is 1.2 kg/s. The air enters at 620 K and 0.1 MPa at a rate of 2 kg/s. Determine the heat-transfer rate between the two fluids (kW) and the exit temperature (K) of the air.
