This article is a continuation of the previous study [1] devoted to the physical phenomena, connected with a surface tension of liquid. The meniscus of liquid at a vessel wall is one of the most known effects of such nature. As well as the problem of the form of hanging and sitting drops of liquid, the analysis of meniscus form traditionally is based on the solution of Laplace equation [2]. In the given article the problem of meniscus is examined from the point of view of mechanical balance of a liquid under surface tension, gravity and wettability of a wall surface. The obtained solutions are convenient for computer calculations, and at the same time have necessary universality. More and more exact and detailed knowledge about, apparently, well-known physical phenomena are indispensable for the development of modern technologies and technical equipment. In the full measure it concerns the study of liquid properties caused by surface tension [3].
