A hull and tube heat exchanger is used to heat 10 kg/s of oil (Cp = 2.0 kJ/kg K), from 25°C to 46°C. The exchanger is one-step through the hull and 6-step through the tube. Water enters the side of the hull at 80°C and comes out at 60°C. It is estimated that the total heat transfer coefficient is 1000 W/m2.K. Calculate the ratio of the heat transfer and the transfer area of the latter.

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.
