← ScienceWhich consequence results when a municipal waterline reaches excessive flow speed?
A)Increased pipe wall erosion✓
B)Decreased static water pressure
C)Elevated laminar boundary layer
D)Reduced dissolved oxygen content
💡 Explanation
Excessive flow speed causes a transition to turbulence, therefore increased pipe wall erosion happens because turbulent flow intensifies shear stress; rather than influencing pressure or oxygen, the increased speed triggers turbulence.
