← ScienceWhich outcome occurs when pump flow exceeds design limits?
A)Increased vibration and cavitation erosion✓
B)Improved impeller structural integrity results
C)Reduced motor winding insulation degradation
D)Optimal heat transfer within pump housing
💡 Explanation
Exceeding design flow causes strong pressure gradients and localized boiling due to increased kinetic energy input; this leads to cavitation, where bubble collapse causes vibrational energy and erosion, because the increased fluid speed induces turbulent flow, rather than smooth laminar flow and balanced pressure.
