Hot oil at a rate of 5 kg/s (Cpm= 2 kJ/kg. K) enters in a 2-4 shell and tube heat exchanger at 366 K and is cooled to 344 K by 2 kg/s of water (Cpm= 4 kJ/kg. K) entering at 283 K. The overall heat transfer coefficient U0 is 340 W/m . Calculate the area requied. If the length of each tube is 1.2 m, and the diameter of each tube is 0.1 m, calculate the number of tubes?
