In physics, hydrodynamics of fluid dynamics explains the mechanism of fluid such as flow of liquids and gases. The viscosity of gases increases with increase of temperature because when temperature of gas increases, then rate of diffusion increases. The viscosity of liquids increases with increase in pressure but the viscosity of water decreases with increase in pressure.Ĥ. The viscosity of gases increases with increase in temperatures asģ. 3.2 Momentum transfer between the layers. 2 Viscosity of gases (momentum transfer) 3 Derivation of the viscosity of ideal gases. Η 0 and η t are coefficient of viscosities at 0☌ and t☌, α and β are constants.Ģ. The viscosity of ideal gases is mainly based on the momentum transfer due to diffusion between the fluid layers. Molasses, for example, has a greater viscosity than water. Viscosity can also be thought of as a measure of a fluid’s thickness or its resistance to objects passing through it. Liquids which have high viscosity flow more slowly compared to liquids which are less viscous. 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. Viscosity is the measure of a liquids resistance to flow. The reciprocal of the viscosity is called the fluidity, a measure of the ease of flow. Viscosity arises when there is relative motion between layers of the fluid. Viscous forces are intermolecular forces acting between the molecules of different layers of liquid moving with different velocities. viscosity, resistance of a fluid (liquid or gas) to a change in shape, or movement of neighbouring portions relative to one another. This internal frictional force is called viscous force. What is Viscosity? | Definition, Formula, Units – Hydrodynamics

This page focuses on how to define viscosity, the different types of viscosity, and the different types of liquids which show either Newtonian or non-Newtonian flow behavior. It is the resistance which a fluid shows when being deformed. We are giving a detailed and clear sheet on all Physics Notes that are very useful to understand the Basic Physics Concepts. In scientific terms, viscosity is the measure of a fluid’s internal flow resistance. The property of a fluid by virtue of which an internal frictional force acts between its different layers which opposes their relative motion is called viscosity.
