Which outcome limits pump efficiency when a Newtonian fluid exhibits constant flow?

A)Increased frictional pressure drop✓

B)Elevated fluid bulk modulus

C)Reduced impeller surface tension

D)Decreased cavitation onset threshold

💡 Explanation

Constant fluid flow against pipe walls leads to viscous effects, causing an increased frictional pressure drop because momentum transfer dissipates energy in the fluid. Reynolds number affects viscosity rather than properties like bulk modulus or mitigating cavitation thresholds.
