Water hammer is caused in steam carrying pipelines, because of ______________________?
Correct answer: A. Partial condensation of steam
- A. Partial condensation of steam
- B. Vibration of the pipeline
- C. High degree of superheat of steam
- D. Its exposure to torrential rain
Explanation
Steam can partially condense in a pipeline and form liquid-water slugs; their sudden acceleration produces water hammer and severe pressure shocks. Superheat tends to prevent condensation rather than cause it.
