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.

WebA plot of stress versus shear rate yields a straight line with the slope equal to the viscosity. A viscosity versus shear rate plot yields a horizontal line as the viscosity is independent of shear rate. All gases obey Newton’s law and are Newtonian fluids. Mineral oils and blends of mineral oils are also generally Newtonian in flow behavior. coastal harley-davidsonWebThe study found that there was better repeatability of measurements if the upper shear rate was limited to 511 s-1.
