← ScienceWhich effect limits liquid flow rate in microfluidic devices?
A)Shear thickening hinders fluid movement✓
B)Surface tension overcomes momentum alone
C)Increased kinematic viscosity increases momentum
D)Thermal expansion reduces channel dimensions
💡 Explanation
Shear thickening fluid restricts flow because increased shear stress causes viscosity to increase. Therefore, flow rate decreases at higher pressures rather than obeying linear scaling at this scale because of non-newtonian characteristics.
