In a double-pipe, counter-flow heat exchanger, water entering at 1 kg/s is heated from 23°C to 69°C as it flows thru the inner pipe. Hot oil enters the heat exchanger at 2 kg/s and 110°C. The convection heat transfer coefficients in the cold- and hot-sides are 100 and 50 kW/m².°C, respectively. Calculate the required heat transfer area in m?. Take cp = 4.18 kJ/kg.°C for water, and cp = 1.67 kJ/kg.°C for oil. Round your answer to 2 decimal places. Add your answer

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.
