Question:
A cross-flow air-to-water heat exchanger with an effectiveness of 0.65 is used to heat water (cp = 4180 J/kg·K) with hot air (cp = 1010 J/kg·K). Water enters the heat exchanger at 20°C at a rate of 4 kg/s, while air enters at 100°C at a rate of 9 kg/s. If the overall heat transfer coefficient based on the water side is 260 W/m2·K, determine the heat transfer surface area of the heat exchanger on the water side. Assume both fluids are unmixed.
