(vi) Thyxotropic fluid – This is a fluid in which after reaching a yield value of shear stress, the fluid begins to flow. The fluid flows such that the relationship between the shear stress and the velocity gradient is not linear. Determination of Viscosity: A viscometer is an instrument used to determine the viscosity of a fluid.

Water at a temperature of 20°C has a viscosity of 1.004 x 10^-6 m²/s This evaluates to 1.004000 Centistokes. This value must be converted back to 1.004 x 10^-6 m²/s for use in calculations. The kinematic viscosity can also be determined by dividing the dynamic viscosity by the fluid density. Kinematic Viscosity and Dynamic Viscosity Relationship

• ### What Is Viscosity in Physics? - ThoughtCo

Jul 03, 2019· Viscosity, the "thickness" of fluid, refers to how resistant a fluid is to movement through it. Water has a low or "thin" viscosity, for example, while honey has a "thick" or high viscosity. The law of viscosity has important uses in such areas as inkjet printing, protein formulations and injections, and even food and beverage manufacturing.

Liquid viscosity is a measure of the internal friction of a liquid. Liquids with high viscosities flow slowly, whereas low viscosity liquids flow quickly. Lava has a relatively high viscosity; water has a relatively low one. You can measure the viscosity of a liquid by measuring the velocity of a sphere as it falls through the liquid.
