WebShear Rate. Shear rate is the rate at which one layer of fluid passes on another adjacent layer of fluid; this can find out by both using geometry and speed of the flow. The viscosity of fluid mainly depends upon the shear rate of the fluid. This parameter is very important while designing fluid products like syrups, sunscreen cream, body ... WebShear rate is the rate of deformation of the liquid. Imagine that you drag a boat through the liquid – in a thin liquid, the force required is less than in a thick liquid. And the faster you drag the boat (= the higher the shear …
