A still mill desires to cool 3000 gal/hr of an inorganic liquid from 250oF to 180oF by Lehigh River water flowing through a shell-and-tube exchanger at a rate of 5000 gal/hr. The liquid is somewhat acidic in nature and so an alloy exchanger is probably required. Within the plant is an unused S-and-T, floating-head exchanger have one shell pass and two tube passes. The shell is mild steel, and the tubes are type 304 stainless. Specifications of the surplus exchanger revel a 20-in I.D. shell with 158 1-in 14 BWG tubes 16 ft long laid out on a 1.25 in square pitch. Baffles are placed 6-in apart. Will the surplus exchanger be suitable for the cooling requirements? Assume the inorganic liquid has the physical properties of water.
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.
