← ScienceWhich mechanism predicts increased laminar flow instability using Reynolds number?
A)Viscous shear surpasses inertial forces✓
B)Turbulent eddies dampen wave propagation
C)Boundary layer abruptly becomes thinner
D)Surface tension induces capillary action
💡 Explanation
Laminar flow becomes unstable with high Reynolds numbers because viscous shear forces, indicated by the Reynolds number exceeding a threshold, are overcome by inertial forces, therefore turbulence rises, rather than laminar maintaining due to viscous dominance at lower fluid velocities.
