← ScienceWhich consequence results when impeller cavitation collapses during pumping cycle?
A)Increased pump output pressure achieved
B)Vapor pressure returns to normal
C)Localized material erosion occurs rapidly✓
D)Laminar flow profile turns uniform
💡 Explanation
Material erodes because cavitation involves the formation and collapse of vapor bubbles. Microjets created during bubble implosion cause intense pressure waves; therefore localized erosion happen, rather than increased output because collapsing microjets damage the impeller.
