← ScienceWhich outcome arises when internal pressure rises within a pump experiencing cavitation?
A)Dramatic increase in pipe vibrations✓
B)Pump efficiency momentarily increases
C)Flow rate remains precisely constant
D)Viscosity sharply decreases near impeller
💡 Explanation
Pump cavitation causes vapor bubbles to collapse violently, instigating turbulence due to implosion forces; because of this, localized pressure spikes excite the pipe system, therefore increasing vibrations considerably rather than maintaining flow or increasing efficiency.
