← ScienceWhich outcome arises when fluid viscosity overwhelms inertia in pipe flow?
A)Reduced pipe wall shear stress
B)Increased kinetic energy flux
C)Laminar flow regime stabilises✓
D)Elevated convective heat transfer
💡 Explanation
Laminar flow emerges due to viscous damping; momentum diffusion (viscosity) dominates. Inertia diminishes because disturbances are suppressed by viscous forces. Therefore laminar flow stabilizes, rather than transitioning to turbulent, and thus reduces momentum and energy transport.
