Which outcome impairs a microfluidic pipette's function when exceeding flow thresholds?

💡 Explanation

Exceeding flow thresholds induces turbulence because the Reynolds stresses overcome viscous forces; streamlines mix rather than staying smooth. Bernoulli's principle no longer precisely predicts pressure drop; therefore, controlled fluid aspiration fails rather than a different electrical or thermal effect.
