Which consequence results when Reynolds number exceeds critical drag?

A)Laminar flow transitions to turbulence
B)Pressure gradient stabilizes the flux
C)Boundary layer thickness decreases slightly
D)Viscous region widens considerably

💡 Explanation

A high Reynolds number implies inertial forces dominate, and therefore laminar flow transitions to turbulence because amplified disturbances via the Tollmien-Schlichting waves are generated, rather than viscous forces damping disturbances leading to stability, which happens at lower Re.
