Cavitation is caused by _____________________?
Correct answer: A. Low pressure
- A. Low pressure
- B. Low discharge
- C. High velocity
- D. High pressure
Explanation
Cavitation begins when local pressure falls below the liquid’s vapour pressure, causing vapour bubbles that later collapse and damage surfaces. High velocity can contribute indirectly by creating such low-pressure zones, but low pressure is the direct cause.
