Which phenomenon prevents accurate flow measurement using Bernoulli's equation at high Reynolds numbers?

A)Increased fluid boundary layer thickness
B)Onset of flow induced cavitation
C)Dominance of turbulent kinetic energy
D)Static pressure head loss reduction

💡 Explanation

Turbulence negates the assumptions of steady, laminar flow crucial for Bernoulli’s equation; energy dissipates via eddies due to viscous forces, rather than conforming to streamline assumptions. Therefore, turbulent kinetic energy dominates, rather than a simple pressure-velocity relationship, because the equation is valid only for laminar flow.
