What is Shear Rate and Why is it Important? | Labcompare pdf effects of shear rate on strength properties and

Viscosity is the resistance to flow. In this case, there is some friction between the layers. Therefore, as the upper plate moves with speed or velocity v2 equal to V, cm/s, some of that motion is transferred downward from layer to layer, until the stationary plate is reached. The stationary plate has speed or velocity v1 equal to zero. The distance between plates is x, cm. Therefore, the shear rate in this case isSee more on labcompare pdf effects of shear rate on strength properties andWhat are the properties of shear strength?2.
