Looking at the uncertainty of viscosity measurements tools
Non-Newtonian fluids, which include paint, blood, soup, and drilling fluids, contain a large amount of solids and have a viscosity that changes as they are sheared or stretched. For example, the viscosity of non-drip paint reduces as it becomes thinner when being applied to a wall. The underlying physics of non-Newtonian liquids affects the measurement of viscosity meters, but the resulting uncertainty and inaccuracy have never been systematically evaluated. The highest need for traceable, accurate, non-Newtonian viscosity measurements is in the energy sector. This project aimed to investigate the measurement uncertainties of existing tools and carry out a review of the physics that impacts the viscosity of non-Newtonian liquids to produce a new metrology standard. Ultimately this would improve operational efficiency in the energy sector and enable the construction of more complex oil and gas wells to reach reservoirs in challenging locations
