← ScienceWhich risk increases when flow exceeds transition point?
A)Enhanced pressure vessel wall fatigue✓
B)Improved pump cavitation performance
C)Decreased laminar flow resistance
D)Higher net positive suction head
💡 Explanation
Exceeding the transition point causes turbulence that increases fatigue rate of piping because of increased dynamic fluctuations within the system around the critical Reynold's Number. Stress concentrations become enhanced; therefore promoting fatigue rather than other stable configurations, at lower energy levels.
