Which outcome limits maximum flow in oil pipelines?

💡 Explanation

Increased pipe-wall roughness causes increased frictional losses from turbulent flow via viscous effects (momentum diffusivity), leading to drag amplification; therefore maximum flow is limited, rather than density stratification, because the turbulence dominates at high Reynolds numbers.
