When a capillary is dipped in water, it starts rising up due to pulling force from the solid-vapor interface. If the capillary has insufficient length, as the water rises it accelerates till the end of the capillary.

WebbThe shape of the liquid surface is curved near the place of contact with the solid. This curvature is called meniscus. The meniscus is formed at the surface of the liquid near the walls of a glass beaker. This because whenever a liquid is poured into a glass, two types of forces will act on that. The two forces are: Cohesive force and WebbHere, a self-driven system of a smart liquid gating membrane is further developed by designing a new sytem based on a liquid gating magnetoelastic porous membrane with …
