A shell-and-tube heat exchanger with 2-shell passes and 12-tube passes is used to heat water (cp = 4.18 kJ/kg·K) in the tubes from 20°C to 70°C at a rate of 4.5 kg/s. Heat is supplied by hot oil (cp = 2.3 kJ/kg·K) that enters the shell side at 170°C at a rate of 10 kg/s. For a tube-side overall heat transfer coefficient of 350 W/m2.K, determine the hea
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.
A shell-and-tube heat exchanger with 2-shell passes and 12-tube passes is used to heat water (cp = 4.18 kJ/kg·K) in the tubes from 20°C to 70°C at a rate of 4.5 kg/s. Heat is supplied by hot oil (cp = 2.3 kJ/kg·K) that enters the shell side at 170°C at a rate of 10 kg/s. For a tube-side overall heat transfer coefficient of 350 W/m2.K, determine the heat transfer surface area on the tube side. Assume the correction factor F to be 1. (Round the answer to two decimal places.)
