← ScienceWhich outcome develops from elevated shear in centrifugal pumps?
A)Decreased net positive suction head
B)Increased radial thrust forces
C)Onset of cavitation risk
D)Transition to turbulent flow✓
💡 Explanation
Turbulent flow increases above a critical Reynolds number because increased shear promotes inertial forces over viscous forces, triggering the transition process. Therefore, the instability causes disruptive turbulence rather than laminar flow that cavitation might induce under these conditions.
