Cavitation occurs in a centrifugal pump when the suction pressure is________________?
Correct answer: A. Less than the vapour pressure of the liquid at that temperature
- A. Less than the vapour pressure of the liquid at that temperature
- B. Greater than the vapour pressure of the liquid at that temperature
- C. Equal to the vapour pressure
- D. Equal to the developed head
Explanation
Cavitation begins when the local liquid pressure falls below its vapour pressure at the operating temperature, allowing vapour bubbles to form. In a pump this commonly occurs near the impeller eye on the suction side.
