An oil heater heats 60 kg per minute of oil from 28°C to 70°C in a counter-flow heat exchanger. The average specific heat of the oil is 2.5 kJ/kg-'C. Exhaust gases used for heating enter the heater with an average specific heat of 1 kJ/kg-*C, a mass flow rate of 100 kg/min and an initial temperature of 200°C. The overall heat transfer coefficient is 80 W/m² -C. Determine the heating surface area in m².

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.
