← ScienceWhich outcome during fluid flow results when laminar profiles reach elevated Reynolds numbers?
A)Decreased pressure induced by viscosity
B)Turbulence initiated by shear stresses✓
C)Increased streamline consistency unaffected
D)Suppressed mixing caused solely diffusion
💡 Explanation
Approaching elevated Reynolds numbers reduces fluid stability; therefore turbulence initiates via increased shear stress distorting laminar flow, rather than enhanced pressure or consistent streamline patterns, because molecular diffusion is comparatively weak during turbulence.
