← ScienceWhich hydraulic consequence results when increased flow diminishes the kinematic viscosity?
A)Onset of cavitation increases rapidly
B)Reynolds number exceeds transition range✓
C)Laminar flow profile becomes flatter
D)Pumping losses decrease to minimum
💡 Explanation
Increased flow combined with diminished kinematic viscosity raises the Reynolds number which indicates a transition to turbulent flow. The transition occurs because inertial forces dominate over viscous forces. Therefore, the Reynolds number exceeds the transition range, rather than remaining laminar or decreasing pumping losses.
