Surface Tension & Capillary Action

Surface Tension Surface tension occurs at the interface of the liquid and a gas or at the interface of two liquids. Surface tension (σ) is inversely proportional to temperature. It acts when fluid is at rest. It is a surface phenomenon.

Vortex Motion Definition

Vortex Motion A whirling or rotating mass of fluid is called vortex flow. The flow of the fluid in a curved path. Free Vortex Flow In this flow fluid mass rotates due to the conservation of angular momentum. The velocity profile is inversely proportional to the radius.

Solid Friction and Viscosity Similarities & Dissimilarities

What is Friction? Friction is the force that opposes the motion. It acts between the surfaces in contact. There are basically four types of frictions- Definition of Solid Friction The friction that acts between the surfaces of solid surfaces. Static, Sliding and Rolling Frictions are the examples of Solid Frictions.
