← ScienceAt decreased scales, which outcome arises due to increased Reynolds number?
A)Increased drag on moving objects✓
B)Laminar flow profile emergence
C)Reduced mixing efficiency observed
D)Decreased boundary layer instability
💡 Explanation
Increased Reynolds number at diminished scales transitions flow to turbulence; because inertial forces overwhelm viscosity, therefore drag raises abruptly, rather than retaining laminar state and ordered layers.
