WebViscosity Defined. 1. What is the viscosity of my product? Kinematic viscosity n (nu), resulting from a flow time measurement, takes account of gravity and concerns rather less viscous fluids and simple rheological behavior: Newtonian fluids. It is expressed in Stokes, cStokes or cm2/s. Dynamic viscosity h (Eta) qualifies most formulated products; it is … http://mygivingpoint.org/Book/record/holtchemistrystudyguideconceptreviewstoichiometry.pdf?sequence=1

Webshear rate the viscosity decreases as a result of the breakdown in structure. In the second part of the experiment, the shear rate decreases (as a result of the decreasing stress sweep). The viscosity then increases, but at a slower rate than it dropped ini-tially (see Figure 4). Thus, for one shear the curve will produce two different values ...
