Which consequence results when turbulent flow assumptions violate Bernoulli's equation in a high-speed pump?

A)Increased pump cavitation and wear
B)Stable laminar flow establishment downstream
C)Higher pump efficiency and output
D)Reduced frictional head and pressure loss

💡 Explanation

Increased pump cavitation and wear results as turbulent eddies induce local pressure drops, violating the assumptions in Bernoulli's equation. The mechanism here is increased vorticity. Therefore cavitation occurs more readily, rather than laminar flow, because the assumption fails which relied inviscid flow.
