Detailed explanation-1: -For a Newtonian fluid, the apparent viscosity is constant, and equal to the Newtonian viscosity of the fluid, but for non-Newtonian fluids, the apparent viscosity depends on the shear rate.

Detailed explanation-2: -Water-in-crude oil emulsions often show a shear-thinning non-Newtonian behavior, meaning that the viscosity reduces as the shear rate increases. The influence of shear rate on the viscosity is observed to increase as the concentration of the dispersed phase increases [63].

Detailed explanation-3: -The apparent viscosity of each sample decreases greatly with increasing shear rate. Viscosity increases as the shear rate decreases again, but to values less than those measured in the initial, increasing-rate ramp. This response is thixotropy.
