Webb2 feb. 2011 · If n = 0, the viscosity is, of course, independent of shear-rate; if n = −0.8, an increase in g by a factor of 10 causes a decrease in η by a factor of about 6. For a shear-thickeningor dilatantfluid, in contrast, η increases with increasing γ (see Figure 1). Figure 1. Purely viscous fluids. 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 ...

Webb25 nov. 2024 · The shear rate was varied from 10 to 1000 1/s, with 15 measurements taken at logarithmically spaced intervals in that range. This procedure was repeated three times for each fluid to report average viscosity values at each shear rate and temperature. The standard deviation of the average of the three measurements was around ±0.2 mPa·s.

Webb13 juli 2016 · Shear rate is the rate of strain change over time.
