What causes cavitation in centrifugal pump ?
Correct answer: C. Low suction pressure
- A. High suction pressure
- B. Low barometric pressure
- C. Low suction pressure
- D. High suction velocity
Explanation
Cavitation occurs when the local liquid pressure falls below its vapour pressure, causing vapour bubbles to form and collapse. In a centrifugal pump, this is commonly caused by insufficient suction pressure or available NPSH.
