← ScienceWhich mechanism influences turbulent transition if the Reynolds number increases significantly within a pipe?
A)Suppression of frictional wall shear
B)Amplification of velocity perturbations✓
C)Reduction in fluid dynamic viscosity
D)Inhibition of pressure gradient generation
💡 Explanation
Increased Reynolds number signifies increased inertial forces relative to viscous forces; therefore, the amplification of velocity perturbations due to inertial effects triggers turbulence rather than preventing shear, lowering viscosity or inhibiting pressure as viscous damping reduces with higher Re.
