Write legibly, provide manual step by step solution, and diagram for below given problem. A counterflow heat exchanger is designed to heat fuel oil from 26 deg C to 100 deg C while the heating fluid enters at 138 deg C and leaves at 105 deg C. The fuel oil is 27 deg C API and has a specific heat of 2.3 KJ/kg- K and enters the heat exchanger at the rate of 1000 gallons per hour. Determine the heating surface area if overall coefficient of heat transfer is 420 Kcal/hr-m^2-K.
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.
