← ScienceWhich consequence arises if a pipe's average flow velocity significantly exceeds the estimate predicted by the Hagen-Poiseuille equation?
A)Increased laminar sublayer thickness
B)Onset of turbulent flow✓
C)Decreased form drag coefficient
D)Stable pressure drop reduction
💡 Explanation
Turbulent flow will be the result because, above a certain Reynolds number, inertial forces dominate viscous forces in the fluid flow and cause the laminar flow to transition to turbulent via the instability mechanism. Therefore, turbulence results, rather than a stable laminar flow profile.
