← ScienceWhich risk increases when fluid flow through aged pipelines becomes highly turbulent?
A)Increased laminar flow stabilization downstream
B)Elevated acoustic resonance generation
C)Accelerated erosion of pipe walls✓
D)Reduced pressure head loss overall
💡 Explanation
Increased turbulence creates chaotic pressure fluctuations near the pipe walls, and cavitation then corrodes the pipe material. It does this via boundary-layer separation, because increased shear stress dislodges protective layers; therefore erosion accelerates, rather than acoustic resonance, under these high-stress scenarios.
