← ScienceWhich risk increases when laminar flow transitions in municipal water mains?
A)Erosion corrosion dramatically increases✓
B)Pipe wall temperature decreases
C)Sediment deposition sharply decreases
D)Water hammer pressure reduces
💡 Explanation
Turbulence develops because increased velocity fluctuations cause enhanced mixing and wall shear; therefore erosion corrosion increases rapidly, rather than deposition decreasing, or temperature/pressure immediately changing, conditions that involve different mechanisms.
