Viscosity of Newtonian and Non

At the same time for a non-Newtonian fluid, the viscosity is determined by the flow characteristics Looking at Figure 3, you can observe three very different velocity profiles depending on the fluid behavior For all these fluids, the shear rate at the walls ie the slope of the velocity profile near the wall is going to determine viscosity...
