The centre to centre distance between two consecutive baffles in a shell and tube heat exchanger is called the baffle pitch or baffle spacing, which is more than 1/5th the I.D. of the shell. Which of the following is not a function of the baffles?
ATo reduce the induced vibration in the tubes
BTo increase the tube side heat transfer co-efficient by inducing turbulence
CTo increase the residence time of shell side fluid
DTo provide support to the tube bundle
Correct answer
B. To increase the tube side heat transfer co-efficient by inducing turbulence
Explanation
The correct answer is To increase the tube side heat transfer co-efficient by inducing turbulence.
