← ScienceWhich outcome results when channel flow transition due to increased velocity?
A)Onset of turbulent flow✓
B)Decreased wall shear stress
C)Laminar sub-layer stabilization
D)Reduced frictional pressure drop
💡 Explanation
Turbulent flow initiates because the Reynolds number exceeds a critical value leading to increased inertial forces; therefore, increased velocity causes turbulent transition, rather than stabilizing the flow or decreasing shear because laminar flow is stable below this.
