← ScienceWhich outcome prevails when Reynolds number exceeds threshold?
A)Laminar flow transitions to turbulence✓
B)Viscosity increases fluid momentum
C)Diffusion dominates convective transport
D)Surface tension stabilizes fluid interface
💡 Explanation
Turbulent flow begins because inertia forces dominate viscous damping; therefore disrupts laminar streamlines through increased momentum transfer via eddy formation, rather than stabilized flow. Diffusion will not exclusively dominate because turbulence enhances convection.
