Which consequence results when increased fluid velocity past an airfoil exceeds viscosity limits?

A)Flow regime transitions and turbulence occurs
B)Lift increases proportionally to velocity
C)Pressure near the surface stabilizes
D)Laminar flow becomes perfectly uniform

💡 Explanation

Flow regime transitions and turbulence result because exceeding fluids' viscous sublayer thresholds causes disturbances as predicted through the Reynolds number, therefore turbulent flow occurs, rather than laminar flow which would maintain lift under control surfaces.
