← ScienceWhich outcome results when a centrifugal pump operates with a reduced net positive suction head reaching a specific number?
A)Viscosity significantly decreases fluid pumping
B)Turbulent flow transitions into the laminar
C)Cavitation occurs, damaging pump components✓
D)Bernoulli's principle elevates energy efficacy
💡 Explanation
Cavitation occurs because the liquid's vapor pressure is locally exceeded as it flows within the pump, causing vapor bubble formation and then implosion. Therefore, damage happens rather than efficient flow, because the vapor pressure isn't properly managed.
