← ScienceWhich mechanism triggers erratic forces when a centrifugal pump operates far below its designed flow number?
A)Reynolds number induces turbulent cavitation✓
B)Euler number generates increased shear
C)Nusselt number causes overheating
D)Prandtl number dominates boundary separation
💡 Explanation
Turbulent cavitation becomes dominant below a pump's normal flow rate because reduced pressure increases the bubble formation rate within recirculation zones; therefore cavitation damage and noise increase, rather than effects related to heat transfer dominance.
