Pressure in the siphon

Drašković, Draško (author), Čepič, Mojca (author)

The paper reports on direct measurements of pressure inside the siphon. Two apparatuses were designed. The first one allows for detailed measurements of pressure dependence along the siphon tube, the second is the simplified version of the first, which allows for measurements and for visual demonstration of pressure at a few points along the siphon tube. Discussion of measurements uses two approaches, the standard combination of Bernoulli equation, and the resistance due to the combination of viscous and quadratic drag and using the forces acting on object-like small parts of water.
