![]() When the materials flow breaks stop the watch. Slowly remove the glass and as soon as you do start the stop watch.Remove your finger from the cup and place a beaker under it.Slide the glass plate over the liquid, removing any access from when it was filled.Slightly over-fill the flow cup with your material.Cover the hole at the bottom of your flow cup with your finger.Then verify the substance has no air bubbles in it (ideally freshly strained). The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. Viscosity is an important fluid property when analyzing liquid behavior and fluid motion near solid boundaries. Verify that the cup temperature and the liquids temperature are uniform before testing. Vicosity is a fluid's resistance to flow and can be valued as dynamic (absolute) or kinematic. Then adjust the feet until a level measurement has been achieved. To ensure that everything is level put glass and a bubble level on top of the cup. The use of the ideal gas law and the Redlich-Kwong compressibility factor for gas density calculation, and use of the Sutherland Formula for gas viscosity. Place the flow cup into its stand and ensure that it is level. ![]() Using abrasive cleaning materials such as a wire brush could damage the cup again causing issues in accuracy. Dirty equipment will impact the accuracy of the test. Using a suitable solvent clean the cup, handle and orifice to verify there is no residue. Validate there are no pre-set standards since certain viscosity tests have unique flow time standards. If not listed, select a cup that will give an estimated flow time of 30 - 100 seconds. Determine The Proper Flow Cupįirst check the products technical data sheet to see if a flow cup has been listed. Viscosity tests are used in a variety of industries such as food in order to calculate the right consistency and the painting industry to verify that the product will operate correctly in machinery. This flow helps determine the proper consistency and can verify product quality. The Viscosity of a material is the measurement of its flow. Viscosity measurements are important when checking a products quality and efficiency. In this article we will cover how to conduct a simple and accurate viscosity test with the flow cup.
