Which outcome occurs when the inlet pressure drops excessively within a positive displacement pump?

💡 Explanation

Surface pitting escalates due to cavitation; vapor bubbles form and then collapse violently upon a component's surface, resulting damage. This is because vapor pressure has been reached; therefore pitting occurs rather than improved performance resulting from optimal fluid pressures.
