Which ONE of the following statements about baffles in a shell and tube heat exchanger is FALSE? Baffles
- Aact as a support to the tube bundle
- reduce the pressure drop on the shell-side
- Calter the shell-side flow pattern
- Dhelp in increasing the shell-side heat transfer coefficient
Explanation
Baffles force the shell-side fluid into a cross-flow pattern, which INCREASES turbulence and pressure drop (not reduces it), while also increasing the shell-side heat transfer coefficient and supporting the tube bundle. The statement claiming baffles reduce shell-side pressure drop is false.
