← ScienceWhich outcome results when non-Newtonian fluid's shear rate decreases?
A)Viscosity increase by shear thickening
B)Viscosity decrease by shear thinning
C)Dynamic viscosity becomes independent measurement
D)Fluid approaches Newtonian flow characteristics✓
💡 Explanation
Decreasing shear rate in shear-thinning (non-Newtonian) fluids permits polymer chains to unalign because the mechanism of shear thinning requires alignment to reduce resistance, therefore, the fluid behaves more like a basic fluid rather than the others since they reverse the shear impact.
