Which risk increases when a hydraulic pump encounters vapor bubbles?

💡 Explanation

Vapor bubbles collapsing near the impeller surface cause intense pressure spikes, leading to unstable cavitation. This erodes the metal locally because implosion, rather than the smoothness alternatives B, C, or the effect on bulk thermal expansion represented by D.
