24 Jun 1975TL;DR: In this paper, a hydrostatic suspension system for supporting a cylindrical mass, such as an inertial mass, within a housing filled with viscous fluid while eliminating contact between the mass and housing is described.
Abstract: A hydrostatic suspension system for supporting a cylindrical mass, such as an inertial mass, within a housing filled with viscous fluid while eliminating contact between the mass and housing. With the arrangement described tolerances and concentricities of the mass and housing are relaxed to practical values.

TL;DR: In this article, the authors solved a theoretical analysis of the problem, which is based on the equation for isothermal process and, secondly, on the equality of pressures inside and outside the cylinder.
Abstract: This work is focused on the experimental verification of the balance between the atmospheric pressure acting on the sheet of paper, which encloses the cylinder completely or partially filled with water from below, where the hydrostatic pressure of the water column acts against the atmospheric pressure. First of all this paper solves a theoretical analysis of the problem, which is based, firstly, on the equation for isothermal process and, secondly, on the equality of pressures inside and outside the cylinder. From the measured values the confirmation of the theoretical quadratic dependence of the air pressure inside the cylinder on the level of the liquid in the cylinder is obtained, the maximum change in the volume of air within the cylinder occurs for the height of the water column L of one half of the total height of the vessel H. The measurements were made for different diameters of the cylinder and with plates made of different materials located at the bottom of the cylinder to prevent liquid from flowing out of the cylinder. The measured values were subjected to statistical analysis, which demonstrated the validity of the zero hypothesis, i.e. that the measured values are not statistically significantly different from the theoretically calculated ones at the statistical significance level α = 0.05.
