For the same heat load and mass flow rate in the tube side of a shell and tube heat exchanger, one may use multipass on the tube side, because it
A)Decreases the pressure drop
B)Decreases the outlet temperature of cooling medium
C)Increases the overall heat transfer coefficient
D)None of these

Question

Quizplus · Accepted Answer

Multipass arrangements on the tube side increase the overall heat transfer coefficient by enhancing the heat transfer surface area and turbulence, which improves the efficiency of heat exchange between the fluids.
