Which outcome results with elevated Reynolds number through pump?

A)Increased impeller blade surface cavitation
B)Decreased vibrational harmonics within casing
C)Reduced net positive suction pressure
D)Higher laminar flow near outlet

💡 Explanation

Elevated Reynolds numbers tend to increased turbulence which cause vapor bubbles within pump fluids therefore cavitation increases greatly, rather than other options like decreasing vibrations because harmonics are not impacted primarily by Reynolds number.
