Which phenomenon inhibits flow when critical number surpassed?

A)Reynolds number exceeds a threshold✓

B)Elevated combustion generates laminar flow

C)Lowered cavitation increases fluid viscosity

D)Surface tension approaches the vapor pressure

💡 Explanation

Turbulent flow is triggered when the Reynolds number rises above a critical value, because inertial forces dominate the viscous forces and instabilities grow via shear disruption; therefore turbulent, rather than, laminar flow follows where viscous damping is strong enough.
