An 8-tube shell-and-tube heat exchanger with 2 shell passes, ethyl alcohol (cp=2670) is used with a flow rate of 2.1 kg/s in tubes with a diameter of 5.9 cm. J/kg.°C) is used for heating from 25 °C to 70 °C. Heating, with water entering the body at 95 °C and leaving at 60 °C (cp=4190 J/kg.°C). is done. If the total heat transfer coefficient is 800 W/m2 .°C in case of; a) By logarithmic mean temperature difference (LMTD) method (correction factor, F=1 can be taken), b) Calculate the total length of the heat exchanger using the Ɛ-NTU method
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.
