Communicating vessels

Communicating vessels is a system of containers filled with a homogeneous fluid, connected at the base and subjected to the same atmospheric pressure. When the liquid settles, it balances out to the same level in all of the containers regardless of their shape and volume. If additional liquid is added to one vessel, a new equal level will be established in all the connected vessels. This process is part of Stevin's Law and occurs because gravity and pressure are constant in each vessel (hydrostatic pressure).

If additional liquid is added to one vessel, a new equal level will be established in all the connected vessels. This process is part of Stevin's Law and occurs because gravity and pressure are constant in each vessel (hydrostatic pressure). Blaise Pascal proved in the seventeenth century that the pressure exerted on a molecule of a liquid is transmitted in full and with the same intensity in all directions. Since the days of ancient Rome, the concept of communicating vessels has been used for indoor plumbing, via aquifers and lead pipes. Water will reach the same level in all parts of the system, which acts as communicating vessels, regardless of what the lowest point is of the pipes – although in practical terms the lowest point of the system depends on the ability of the plumbing to withstand the pressure of the liquid. In cities, water towers are frequently used so that city plumbing will function as communicating vessels, distributing water to higher floors of buildings with sufficient pressure. Hydraulic presses, using systems of communicating vessels, are widely used in various applications of industrial processes.
