Which outcome affects accuracy when a microfluidic device operates outside designed thresholds?

A)Onset development of turbulent flow
B)Increased rate of static diffusion
C)Increased laminar sublayer thickness
D)Decreased device surface tension

💡 Explanation

The onset of turbulent flow negatively affects reproducibility because a transition past the critical Reynolds number causes chaotic mixing, therefore accuracy diminishes with turbulence rather than predictable laminar flow, which is the intended regime.
