← ScienceWhich mechanism dictates drag increase when exceeding Reynolds number?
A)Laminar flow transitions to turbulence✓
B)Viscosity effects become less significant
C)Surface tension resists fluid detachment
D)Cavitation bubbles locally reduce pressure
💡 Explanation
Above the critical Reynolds number, inertial forces dominate, therefore laminar flow transitions to turbulence, increasing the drag coefficient significantly because of increased momentum transfer, rather than smoother laminar behavior. Viscosity is always present.
