Which consequence results when a racing car's diffuser exceeds its design Reynolds number?

💡 Explanation

A high Reynolds number implies dominance of inertial forces; therefore, exceeding it in a diffuser induces a transition to turbulent flow because of increased instability to viscous stresses, rather than an idealized laminar flow and attached boundary layer.
