Which consequence results when exceeding a pump's allowed NPSH?

💡 Explanation

Cavitation occurs because a low Net Positive Suction Head causes the liquid's static pressure to fall below its vapor pressure; therefore, bubbles form and collapse violently on the impeller due to vaporisation rather than smoother turbulent flow.
