Which consequence results when Reynolds number exceeds fuel pump design limits?

A)Flow becomes fully developed laminar
B)Pump efficiency degrades owing cavitation
C)Viscosity increases within the impeller
D)Compressibility becomes essentially negligible

💡 Explanation

When the Reynolds number exceeds operational thresholds, increased turbulent flow causes cavitation, reducing overall pumping efficiency because the pump cannot maintain required pressure; therefore cavitation weakens pumping, rather than fully developed flow.
