Which outcome reduces drag when exceeding Reynolds number threshold?

💡 Explanation

At high Reynolds number Inertial forces dominate; therefore boundary layer transition to turbulence cause a thinner wake and reduces drag, rather than laminar flow persisting because viscous effects would increase pressure drag.
