← ScienceWhich risk increases when water pipelines experience rapid depressurization?
A)Water hammer intensity increases rapidly
B)Cavitation damage accelerates significantly✓
C)Erosion due to increased flowrate
D)Corrosion rates sharply diminish internally
💡 Explanation
Cavitation risk rises when pressures fall below the water vapor pressure; the phase change causes vapor bubbles, their subsequent collapse performs damage through micro-jetting, damaging materials rather than a less severe fluid impact, because water hammer pressure oscillations don't cause this.
