← ScienceWhich outcome results when turbulence overwhelms a boundary layer?
A)Increased vessel drag and erosion✓
B)Improved engine combustion efficiency
C)Enhanced convective heat transfer rate
D)Reduced pump cavitation and vibration
💡 Explanation
Increased vessel drag and erosion occurs because turbulent flow causes boundary layer separation, resulting in increased pressure drag rather than streamlined flow; therefore, drag increases substantially at higher speeds, rather than offering reduced friction.
