Heat Transfer

Q1: Baffles are provided in heat exchangers to increase the

A fouling factor

B heat transfer area

C heat transfer co-efficient

D heat transfer rate

ANS:C - heat transfer co-efficient

Baffles are provided in heat exchangers primarily to increase the heat transfer rate. Baffles help in promoting fluid mixing and disrupting the flow, which enhances heat transfer by improving fluid distribution and increasing turbulence. This results in more efficient heat transfer between the two fluids in the heat exchanger. So, the correct answer is: "heat transfer rate"
