Which outcome risks hydraulic pump failure if the Reynolds number exceeds a threshold?

A)Increased cavitation damage within the pump
B)Reduced volumetric efficiency occurs rapidly
C)Stable laminar flow becomes guaranteed
D)Suction pressure remains effectively constant

💡 Explanation

Increased cavitation damage results, because high Reynolds number indicates turbulent flow; localized pressure drops cause vapor bubbles to form via cavitation which then collapse violently, therefore damaging the pump material, rather than maintaining stable laminar flow.
