← ScienceWhich consequence results when a fluid exceeds a critical Reynolds number?
A)Laminar flow becomes turbulent flow✓
B)Viscosity exponentially increases
C)Surface tension significantly decreases
D)Fluid density abruptly becomes homogeneous
💡 Explanation
The transition from laminar to turbulent flow occurs, because the inertial forces overwhelm viscous forces, leading to the onset of unstable fluctuations, a process of flow instability. Therefore, the answer is transition to turbulent flow, rather than viscosity changes because of velocity effects alone.
