← ScienceWhich outcome results when rapid depressurization causes water hammer?
A)Cavitation erodes the pipe wall✓
B)Increased hydrostatic pressure bursts seals
C)Radiative heat transfer increases rapidly
D)Water maintains liquid phase throughout
💡 Explanation
Cavitation erodes the pipe wall because localized boiling reduces pressure. Vapour bubble implosion transfers energy via mechanical means to the metal; therefore, cavitation is the outcome rather than uniform phase change because pressure drops locally, rather than systemically.
