Webb13 juli 2016 · Shear rate is the rate of strain change over time. To generate a flow curve, a sample must be subjected to different shear stresses, and the resulting shear rate measured at each applied stress. Alternatively, the shear rate can be controlled and the stress measured. These measurements are usually made with a rotational viscometer or … WebbShear 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 ...
