Which of the following parameters is increased by use of finned tube in a multipass shell and tube heat exchanger?
A)Tube side pressure drop and the heat transfer rate
B)Convective heat transfer co-efficient
C)Effective tube surface area for convective heat transfer
D)All (A) (B) and (C)

Question

Quizplus · Accepted Answer

Finned tubes increase the tube side pressure drop due to added surface roughness and flow disruption, enhance the convective heat transfer coefficient by increasing turbulence, and effectively increase the tube surface area available for heat transfer, thus impacting all the mentioned parameters.
