Adding wetting agents to lower the contact angle and allow liquids to spread are also useful in many areas. In order for a liquid to come gushing out of a tube, it would have to be in a state of overpressure, which would produce an inverted meniscus. Indeed, when a drop becomes small the laplace pressure in the droplet grows according to p. Destination page number search scope search text search scope search text. Consequently, it is a crucial parameter for understanding, modelling and simulating. Springer new york berlin heidelberg hong kong london milan paris tokyo.

A discussion of cohesive forces and surface tension is included, as well as surface acting agents surfactants and their ability to weaken the surface tension of water. When a liquid is in contact with a solid, if the forces of adhesion between the molecules of the liquid and the solid are greater than the forces of cohesion among the liquid molecules themselves, the liquid molecules crowd towards the solid surface.

Understanding why and when a liquid decides to wet a surface can greatly improve our knowledge of everyday events. From the viewpoint of mechanics, elastocapillarity phenomena essentially involve competition between the elastic strain energy in the bulk and the energy on the surfacesinterfaces. Students observe the effects of surface tension using common household materials. In fact, the process is not reversible and, therefore, the work spent resulted in less than complete removal of the wetting phase. Introduction to capillarity and wetting phenomena electrowetting.

This phenomenon has implications for the treatment of textile fibers the process. Because gas, water and hydrate phases are frequently though not universally observed to coexist within the hsz, we focus on the phenomena associated with twophase flow. Capillary action, or capillarity, is a phenomenon where liquid spontaneously rises in. But such a scenario would be incompatible with a rising liquid which, as we know, implies an underpressure to balance the hydrostatic pressure.
