Which effect results when a microscopic channel restricts viscous fluid flow?

💡 Explanation

Poiseuille's Law dictates the resulting pressure drop, because viscous forces resisting flow necessitate a larger pressure gradient for equivalent flow rates when confined; therefore pressure differences emerge quickly in narrow channels, rather than turbulence increases, which emerge only beyond threshold Reynolds numbers.
