Diesel flows at the rate of 3 kg/sec through a double pipe counter flow heat exchanger. Diesel is heated from 60degC to 75degC 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 115degC and leaves at 70degC.the overall heat transfer co-efficient is 340 W/m2K. Calculate the heat exchanger area
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.
