← ScienceWhich outcome occurs when pump flow exceeds thresholds?
A)Cavitation damage increases exponentially✓
B)Specific gravity remains steady
C)Valve efficiency reaches 90%
D)Net positive suction head rises
💡 Explanation
Turbulent flow at high Reynolds numbers induces cavitation because localized pressure drops below liquid vapor pressure, forming bubbles; therefore cavitation damages increase, rather than increases in efficiency which requires laminar flows.
