Evaluation of measurement uncertainty in the determination of the rheological constants of anomalously viscous liquids

In this article the necessity of the most accurate determination of rheological constants for the subsequent hydraulic calculations of the flow of non-Newtonian fluids with plastic properties is noted. The estimation of the measurement error of all physical quantities and geometric dimensions of the viscometer and their contribution to the resulting error in determining the rheological constants of the Shvedov-Bingham medium.
