← ScienceWhich outcome occurs downstream when a fluid's Reynolds number greatly exceeds a pipe's critical value?
A)Increased turbulent kinetic energy dissipation✓
B)Laminar flow profile stabilization
C)Reduced frictional pressure loss
D)Enhanced homogeneous mixing efficiency
💡 Explanation
Increased turbulent kinetic energy dissipation occurs because enhanced inertia promotes chaotic motion within the fluid, and viscous forces covert this kinetic energy into heat energy via the mechanism of turbulent dissipation. Consequently, kinetic energy decreases rapidly rather than stabilizing or increasing it.
