Completely solve and box the final answer. Write legibly Diesel flows at the rate of 3 kg/sec through a double pipe counter-flow heat exchanger. Diesel is heated from 60°C to 75°C by a water (Cp = 4.187 kJ/kg-K) flowing through the tube. The specific heat of the diesel is 1.780 kJ/kg-K. The water enters at 115°C and leaves at 70°C. The overall heat transfer coefficient is 340 W/m2-K. Calculate the heat exchanger area and the rate of heat transfer.
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.
