Which risk increases when a fluid's Reynolds number exceeds limits?

💡 Explanation

Exceeding velocity thresholds leads to a sharp transition because the mechanism, turbulent transition, is triggered where inertial forces overcome viscous forces; therefore, turbulent eddies are more likely, rather than remaining stable laminar flow.
