an oil heat 150 kg of oil per minute from 30 C to 120 C in a counterflow heat exchanger. the average specific heat of the oil is 3.5 kj per cu. Exhaust gases used for heating enter the heater with 300 kg/min and an initial temperature of 220 C. the overall heat transfer coefficient is 84 watts per m per C. determine the heat surface area in m. (hint: use LMTD)
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.
