Definition: Viscosity is a measurement of how resistant a fluid is to attempts to move through it. A fluid with a low viscosity is said to be thin, while a high viscosity fluid is said to be thick.. It is easier to move through a low viscosity fluid (like water) than a high viscosity fluid (like honey).
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. For liquids, it corresponds to the informal concept of thickness.For example, honey has a much higher viscosity than water.or example, water at 20 Â°C has a viscosity of 1.002 mPaÂ·s, while a typical motor oil could have a viscosity of about 250 mPaÂ·s. The units used in practice are either PaÂ·s and its submultiples or the cgs Poise referred to below, and its submultiples.
