← ScienceWhich effect results when a high Reynolds number fluid flows through a valve?
A)Valve erosion from cavitation increases✓
B)Viscosity-driven laminar flow stabilizes
C)Energy losses due to friction decrease
D)Valve's pressure drop coefficient decreases
💡 Explanation
Increased Reynolds number implies higher flow velocity, therefore causing lower pressure regions downstream leading to cavitation; collapsing bubbles erode the valve material, rather than laminar flow stabilizing, this is a turbulent regime.
