Which outcome results when impeller cavitation compromises centrifugal pump efficiency?

A)Premature wear increases drastically
B)Net Positive Suction Head improves
C)Volumetric flow reaches capacity
D)Fluid viscosity decreases markedly

💡 Explanation

Cavitation collapse induces material fatigue because repeated implosions transmit shockwaves causing micro-cracking, therefore impeller wear accelerates rather than viscosity changing; the Net Positive Suction Head decreases instead.
