Introduction of viscosity

WebIntroduction. Viscosity is the phenomenon which is not only related to resistance to the flow of liquid but even related to resistance to the flow of gas, shape change, or … WebThe viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. Viscosity quantifies the internal frictional force between adjacent layers of fluid that are in relative motion. For instance, when a viscous fluid is forced …

Webviscosity, resistance of a fluid to flow. This resistance acts against the motion of any solid object through the fluid and also against motion of the fluid itself past stationary obstacles. Viscosity also acts internally on the fluid between slower and faster moving adjacent layers. All fluids, i.e., all liquids and gases, exhibit viscosity to ...
