Which outcome occurs involving drag when a vehicle exceeds a Reynolds number threshold?

A)Turbulent boundary layer drag increases
B)Laminar boundary layer drag persists
C)Pressure drag linearly decreases
D)Lift transitions to supersonic instability

💡 Explanation

When the Reynolds number exceeds a critical threshold, the boundary layer transitions to turbulence. Viscous forces become less dominant because inertial forces lead to chaotic eddies. Therefore, increased momentum transfer causes higher skin friction, or turbulent boundary layer drag, rather than laminar flow.
