Which consequence results when pressure threshold is exceeded in turbulent flow through a centrifugal pump?

💡 Explanation

When the pressure threshold increases, cavitation bubbles form downstream, collapsing violently on the impeller surfaces via the Nucleation mechanism, resulting in increased impeller erosion, because the bubbles' implosion causes localized high-energy impacts, therefore the answer is erosion, rather than viscosity changes or reduced frequency under standard operating pressures.
