Across-flow air-to-water heat exchanger (both fluids unmixed) with an effectiveness of 0.65 is used to heat water (cp 4180 j/kg. k) with hot air (c 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.
