Cavitation in a centrifugal pump can be avoided by keeping the__________________?
Correct answer: A. Inlet pressure high
- A. Inlet pressure high
- B. Outlet pressure low
- C. Inlet pressure low
- D. Outlet pressure high
Explanation
Cavitation occurs when pressure at the pump suction falls below the liquid vapour pressure. Raising the inlet pressure increases the available net positive suction head and prevents vapour-bubble formation.
