# FME33 Démonstration du Principe de Pascal

## SYSTEMES INNOVANTS

The Pascal's Principle Demonstration Unit, "FME33", designed by EDIBON allows to demonstrate Pascal's principle, i.e. that the pressure in an incompressible fluid is independent of the column size section but depends only on its height (liquid level) and on the type of fluid.

## Description Générale

The Pascal's Principle Demonstration Unit, "FME33", designed by EDIBON allows to demonstrate Pascal's principle, i.e. that the pressure in an incompressible fluid is independent of the column size section but depends only on its height (liquid level) and on the type of fluid. This is possible by comparing three tanks with the same diameter at the base but with different shapes. It also enables the hydrostatic pressure to be quantitatively measured and the linear connection between the pressure and the filling height to be studied.

This unit is made up of a body with a diaphragm or membrane to which any of the three vessels can be attached. The membrane transfers the force to a lever arm that is balanced with masses and a spirit level.

A movable pointer adjustable in height located in a vertical rod allows to fix the height of the water in the vessels to the same level, so that the force or pressure is common for the three vessels regardless their shape.
