Which risk drastically increases within a pump operating far outside design specifications?

A)Unstable flow increases cavitation events
B)Increased shaft eccentricity induces resonance
C)Vane shear intensifies diffusion process
D)Accelerated galvanic reduces anode efficiency

💡 Explanation

Cavitation risk increases sharply when turbulence escalates outside optimal operating ranges. Increased turbulence sets off intense variations in fluid pressure, causing local boiling— cavitation—because fluid pressure collapses unpredictably; therefore, cavitation is more likely, rather than other mechanical degradations occurring.
