Which risk increases within an oil pipeline when the fluid velocity surpasses critical values?

💡 Explanation

Increased fluid velocity triggers a transition to turbulent flow. The increased molecular collisions cause energy dissipation as heat because viscous forces dominate energy transfer via increased mixing, therefore increasing heat production, rather than efficient laminar flow.
