← ScienceWhich outcome from elevated liquid viscosity occurs within microfluidic droplet generators?
A)Smaller droplet size uniformity declines✓
B)Increased Laplace pressure resists breakup
C)Increased interfacial tension eases dripping
D)Reduced Rayleigh instability dominates pinching
💡 Explanation
Increased viscosity elevates internal friction resisting droplet pinch-off; therefore smaller droplet size suffers, because reduced stresses are less able to overcome viscous shear within the generated droplets, rather than interfacial tensions causing increased issues at lower viscosities.
