Shear Rate - What is it? Should You Care? All About Viscosity

WebShear rate is the rate at which a progressive shearing deformation is applied to some material. The shear rate for a fluid flowing between two parallel plates, one moving at a constant speed and the other one stationary (Couette flow), is related to the velocity of the moving plate and the distance between the two parallel plates Related formulas Web(1) shear rate inﬂuences the average apparent viscosity of non-Newtonian ﬂuids and hence affects power absorption, mixing characteristics and mass transfer phenomena … WebAug 13, 2002 · The shear rate will have its higher values in the neighborhood of the spindle, and lower values farther away from it. That is why an open cup and spindle rehometer, like most Brookfield can only provide relative measurements, rather than exact values. If you are interested in a more detailed discussion let me know.
