← ScienceWhich mechanism causes turbulent flow rather than laminar flow in a hydraulic system surpassing its design limits and pressure?
A)Increased inertial overcomes viscous damping✓
B)Decreased surface tension reduces coherence
C)Heightened adhesion causes boundary slippage
D)Lowered pressure generates phase transition
💡 Explanation
Transition occurs because the Reynolds number increases, leading to turbulence; the mechanism converts kinetic energy to chaotic motion overcoming viscous damping. Therefore, inertial overcomes viscous damping because high fluid speeds dominate dissipation, rather than other surface phenomena.
