A shell-and-tube heat exchanger is used to cool hot water by cold water. The heat exchanger has one shell-side pass and two tube-side passes. The how water at 160°C enters the shell-side with a flowrate of 1.5 kg/s while the cold water at 85°C and 3 kg/s enters the tube-side. If the inner tube outer surface area and the corresponding overall heat transfer coefficient are 10.5 m2 and 840 W/m2K, respectively, calculate the exit temperatures of both fluids. (Take the specific heats of hot and cold water are 4340 J/kgK and 4201 J/kgK, respectively)
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.
