1Single-shell heat exchanger with two tube passes, water at 30°C is used to cool 10 kg/s of nitrogen at 200°C at atmospheric pressure. Determine the number of tubes needed to cool the gas down to 90∘C while raising the temperature of water to 60°C using a 2 m long tube of 2 cm diameter. The overall heat transfer coefficient is 100 W/m#⋅ K. The values of specific heat for nitrogen and water are, 1045 J/kg ⋅ K and 4180 J/kg ⋅ K,
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.
