Which risk increases when a fluid's velocity exceeds levels predicted by a simplified Bernoulli equation?

A)Laminar flow destabilizes gradually
B)Viscosity perfectly offsets inertia
C)Turbulence initiates, increasing drag
D)Pressure gradients stay time-invariant

💡 Explanation

When actual velocity exceeds ideal Bernoulli predictions, turbulence initiates because inertial forces become dominant driving flow instabilities--a phenomenon not captured by the laminar assumptions within the equation. Therefore, flow drag rises rapidly with Reynolds number rather than adhering streamlines.
