← ScienceWhich mechanism causes increased pipe erosion when flow velocity significantly exceeds the maximum design parameter?
A)Onset of turbulent flow✓
B)Reduction in surface tension
C)Increased fluid lubricity effects
D)Decreased hydrostatic pressure
💡 Explanation
Turbulence occurs in high-velocity flows due to exceeding the Reynolds number; therefore, irregular eddies form causing cavitation and impacting the pipe wall with enhanced kinetic energy, rather than a property dependent on lubricity or hydrostatic pressure.
