Vibrations in the tubes of a shell and tube heat exchanger is induced due to the _________________?
Correct answer: D. All A., B. and C.
- A. Flow of fluid on the tube and shell sides
- B. Oscillations in the flow of shell/tube sides fluid
- C. Vibrations transmitted through piping and/or supports due to external reasons
- D. All A., B. and C.
Explanation
Tube vibration can arise from fluid-flow excitation on either side, oscillatory flow, or vibration transmitted from external piping and supports. Therefore, all three listed mechanisms are possible.
