Which consequence results when prolonged turbulent flow erodes a pump impeller?

💡 Explanation

Increased cavitation risk occurs, because the **turbulent boundary layer separation** grows larger as the impeller roughens; therefore pressure drops locally intensify and causes cavitation, rather than improved lubrication or stabilized pressure oscillation.
