← ScienceWhich risk increases when a fluid's Reynolds number exceeds pipe design constraints?
A)Laminar flow profile is reinforced
B)Friction factor linearly declines
C)Increased drag from amplified turbulence✓
D)Viscosity effects become negligible here
💡 Explanation
Increased turbulence will elevate the frictional head losses, because the chaotic fluid changes the kinetic energy into frictional heating, resulting in increased drag, therefore turbulent drag worsens over laminar. Pressure remains rather than linear declines in the smooth pipe condition.
