Fluid mechanics/Unit 1/Surface Tension/Lecture 6

urface tension is a fundamental physical property of liquids that describes the cohesive force at the liquid's surface. It results from the attraction between the molecules of the liquid, which causes the surface to contract and resist external force. This phenomenon is responsible for various everyday observations, such as the formation of droplets, the ability of insects to walk on water, and the rise of liquid in a capillary tube. Surface tension plays a crucial role in numerous scientific and industrial applications, including the study of biological membranes, the formulation of detergents and emulsions, and the development of new materials and technologies.
