90,000 kg/h of a hydrocarbon are cooled from 70°C to 40°C by means of a stream of water that is heated from 20°C to 35°C. A 1-2 shell and tube heat exchanger with 4m long tubes, 2.54cm outside diameter and 2.21cm inside diameter should be used. Water flows on the tube side, calculate the number of tubes and water flow area. Cphc=0.45 kcal/kgºC and U=1400 kcal/hm² ºC
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.
