Which outcome results when fluid velocity exceeds limits modeled by the Reynolds number equation?

A)Reduced convective heat transfer efficiency
B)Onset of turbulent flow conditions
C)Increased laminar boundary layer thickness
D)Decreased fluid dynamic drag coefficient

💡 Explanation

Transition occurs because exceeding the Reynolds number causes a shift towards inertial forces dominating viscous forces thereby promoting turbulent flow, rather than laminar flow; therefore only turbulence increases rather than other flow regimes under identical pressure gradients.
