Which 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.
