Water at the rate of 86 kg/min is heated from 20 to 70-C by an oil having a specific heat of 1.9 kJ/kg--C. The fluids are used in a counterflow double-pipe heat exchanger, and the oil enters the exchanger at 110-C and leaves at 70-C. The overall heat-transfer coefficient is 230 W/m2.-C. Calculate the heat transfer area, m2. (A) 15.82 (B) 49.07 29.07 (D) 35.82

Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
