viscosity, 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. The reciprocal of the viscosity is called the fluidity, a measure of the ease of flow. Molasses, for example, has a greater viscosity than water.

Jun 23, 2022 · Liquids which flow very slowly, like glycerin or honey, have high viscosities. Those like ether or gasoline which flow very readily have low viscosities. Viscosity is governed by the strength of intermolecular forces and especially by the shapes of the molecules of a liquid.
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.
Nov 3, 2021 · Viscosity is the resistance of particles in a fluid to flow or move in response to an external force exerted on them. This resistance is because of the way the particles are arranged. If the particles are closer together, the fluid tends to be more viscous. The resistance is also correlated with the intermolecular forces. Molecules of the same ...
Jan 30, 2023 · Viscosity can be not only a fluid’s resistance to flow but also a gas’ resistance to flow, change shape or movement. The opposite of viscosity is fluidity which measures the ease of flow while liquids such as motor oil or honey which are “sluggish” and high in viscosity are known as viscous.
Aug 3, 2021 · By definition, viscosity is a fluid’s resistance to flow or deformation. A fluid with a high viscosity, such as honey, flows as a slower rate than a less viscous fluid, such as water. The word “viscosity” comes from the Latin word for mistletoe, viscum. Mistletoe berries yield a viscous glue, also called viscum.

Oct 5, 2023 · 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.
