← ScienceWhich regime initiates turbulence when Reynolds number increases?
A)Dominant inertial forces, not viscous✓
B)Laminar flow becomes more stable
C)Decreased fluid momentum dissipation rate
D)Viscous forces exceed inertial forces
💡 Explanation
Turbulence occurs when inertial forces dominate, because the fluid's momentum overcomes the viscous damping; this agrees with the Reynolds number; hence, the velocity increases, therefore turbulence initiates rather than a laminar regime caused by strong viscous damping.
