1) 2.5 m/s of air at 150°C is used to heat 0.35 kg/s of 20°C water. The heat exchanger is a finned-tube cross flow heat exchanger with both sides unmixed. The overall heat transfer coefficient associated with the hot side is 120 W/(m2 °C). The hot-side area is 20 m². Assume a constant specific heat for air and water of Gezic = 1.005 kJ/(kg °C), Senator = 4.2 kJ/(kg °C). The pressure of the hot air is P = 1.0...
