A siphon consists of a tube connecting two containers with liquids at different levels. Once the tube is filled, for example, by suction, the liquid flows into the lower container until the liquid levels are equalized. The driving force is the difference of hydrostatic pressure, as determined by Pascal's principle. The flow rate can be calculated using Bernoulli's equation.
