WebThere is a force, called viscous drag F V F V size 12{F rSub { size 8{V} } } {}, to the left on the ball due to the fluid’s viscosity. (b) At a higher speed, the flow becomes partially turbulent, creating a wake starting where the flow lines separate from the surface. WebThe viscosity is independent of the shear rate. Non-Newtonian fluids do not follow Newton’s law and, thus, their viscosity (ratio of shear stress to shear rate) is not constant and is dependent on the shear rate.
