A 1-2 shell and tube heat exchanger is used to heat water from 60 to 90°C. Oil (Cp=2.3 kJ/kg-K) is used as the heating fluid and flows in the shell side at 150°C. The mass flow rate of the water is 5000 kg/hr while that of the oil is 10,000 kg/hr. The tubes are 1% BWG 10 copper pipes (k = 385 W/m-K). The shell side heat transfer coefficient is 2500 W/m²-K while the tube side heat transfer coefficient is 1000 W/m²-K. Calculate: a. the exit temperature of the oil b. the total length of tubes required

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.
Question
Transcribed Image Text:A 1-2 shell and tube heat exchanger is used to heat water from 60 to 90°C. Oil
(Cp=2.3 kJ/kg-K) is used as the heating fluid and flows in the shell side at 150°C. The
mass flow rate of the water is 5000 kg/hr while that of the oil is 10,000 kg/hr. The tubes
are 1½ BWG 10 copper pipes (k = 385 W/m-K). The shell side heat transfer coefficient is
2500 W/m²-K while the tube side heat transfer coefficient is 1000 W/m²-K. Calculate:
a. the exit temperature of the oil
b. the total length of tubes required
