Which outcome results when exceeding Reynold's number within a closed ventilation duct?

💡 Explanation

Transition to turbulence increases frictional losses because the increased mixing enhances momentum transfer and energy dissipation via viscous shear; therefore pressure drop increases, rather than flow remaining laminar or pressure drops reducing.
