Which consequence results when exceeding a pump's design flow-rate?

💡 Explanation

Exceeding design flow induces cavitation which collapses violently causing localized high stress resulting microscopic material removal i.e. increased corrosion rates within the impeller; this is Acoustic Cavitation. Therefore, option A describes fluid dynamics driving corrosion rates rather than head decline or maintaining efficiency.
