A body-and-tube heat exchanger with 2 shells and 8 tubes is used to heat ethyl alcohol (cp=2670J/kg.°C) from 25 °C to 70 °C with a flow rate of 2.1 kg/s in pipes with a diameter of 3 cm. Heating It is made with water that enters the body at 95 °C and leaves at 60 °C (cp=4190J/kg.°C). If the total heat transfer coefficient is 800 W/m2.°C, 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.
