Understanding what is viscosity requires examining multiple perspectives and considerations. Viscosity - Wikipedia. Viscosity is the material property which relates the viscous stresses in a material to the rate of change of a deformation (the strain rate). Although it applies to general flows, it is easy to visualize and define in a simple shearing flow, such as a planar Couette flow. Viscosity | Definition, Facts, Formula, Units, & Examples .... Viscosity is the resistance of a fluid (liquid or gas) to a change in shape or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow.
Viscosity: Definition, Examples, and Formula - Science Facts. Viscosity is a physical quantity that describes a fluid’s resistance to flow. It is a property that resists the relative displacement of the different layers of the fluid.
It can be considered as the fluid friction occurring inside the fluid due to the internal friction between the molecules. Viscosity refers to a fluid's resistance to flow, indicating how easily it deforms or changes shape when exposed to stress. A high viscosity means the fluid flows slowly, such as honey, whereas a low viscosity allows the fluid to flow more freely, like water.
In relation to this, viscosity: Why Liquids Resist Flow and the Role of .... Viscosity is a property of a fluid that describes its resistance to flow. You can think of it as the internal resistance. Water has a relatively low resistance and flows readily. From another angle, syrup has a high resistance and has more difficulty flowing.

More precisely, it measures resistance to flow arising due to the internal friction between the fluid layers as they slip past one another when fluid flows. Moreover, the Resistance to Flow Explained. Viscosity is a property of all fluids, encompassing both liquids and gases, that determines a material’s resistance to flow or to a change in shape.
This property can be understood as the fluid equivalent of internal friction, governing how easily a substance moves or deforms when subjected to an external force.
