WebMar 28, 2024 · 511 x dial reading / shear rate (sec-1) since 511 sec-1 = 300 rpm or (300 x dial reading) / Fann shear rpm. The viscometer is designed to give the viscosity of a Newtonian fluid when used at 300 rpm. For Non-Newtonian fluids, the ratio of shear-stress to shear-rate is not constant and varies for each shear rate. Webcontinuous shear stress or shear rate ramp, from low to high stress or rate T.he yield stress is usually determined by fitting the stress/rate curves with Bingham, Casson or Herschel-Bulkley models. Also manual extrapolation of the stress curve to zero shear rate (shown in figure 1) is frequently used to obtain a yield stress.
