ASTM D2196-Test methods for rheological properties on non-newtonian materials by rotational Brookfield Viscometer. ASTM D2393-Test methods for viscosity for epoxy resins and related components. ASTM D1824-Test method for apparent viscosity of plastisols and organosols at low shear rates by Brookfield Viscometer. to continually assess their products and keep the quality the best! These companies depend on Associated Polymer Labs, Inc. Example: High Viscosity liquid requires more power to pump than a low viscosity liquidĬompanies depend on Quality of their products and to file Patent claims. The unit for density is g/mL.Brookfield Viscometer- Viscosity studies are a direct assessment of processibility. The density of both the sphere and the liquid are needed to perform the viscosity calculation. 
Some common liquids you could try including water, honey, corn syrup, cooking oil, and milk.Ĭalculate the density of your chosen sphere. Try testing many different liquids with different flow rates to see how their viscosities differ. The liquid must be clear enough to see the marble as it’s dropped through the liquid.You can use a watch instead of a stopwatch, but your measurements will be more accurate with a stopwatch.A graduated cylinder is a plastic container that has graded markings on the side that allow you to measure volume.Make sure its diameter is no greater than half the diameter of the graduate cylinder so it can easily be dropped into the cylinder.
The sphere can be a small marble or steel ball. X Research source This experiment has many steps, but when followed correctly, they will allow you to calculate the viscosity of any liquid. To calculate viscosity of a liquid, you will need a sphere, a graduated cylinder, a ruler, a stopwatch, the liquid in question, a scale, and a calculator. Gather the necessary materials for the experiment.
