Heat Transfer - Engineering

Q1:

In case of a multipass shell and tube heat exchanger, providing a baffle on the shell side __________ the heat transfer rate.

A increases

B decreases

C does not affect

D may increase or decrease, depends on the type of baffle

ANS:A - increases

A baffle on the shell side of a multipass shell and tube heat exchanger typically increases the heat transfer rate. Baffles are designed to enhance fluid mixing and promote turbulence within the shell side flow, which improves heat transfer efficiency by maximizing the contact between the fluid streams. Therefore, the correct option is: "increases."
