← ScienceWhich outcome occurs when engine oil flow exceeds a critical Reynolds number?
A)Onset of turbulent flow regime✓
B)Improved lubrication film thickness
C)Reduced oil pump hydraulic efficiency
D)Laminar flow profile is stabilized
💡 Explanation
A transition to turbulence occurs because, beyond a specific Reynolds number, inertial forces dominate viscous forces which disrupt the laminar flow structure; therefore, turbulence ensues rather than predictable laminar flow, under other lower conditions.
