This question might be better suited for this stack. In the physics stack, I posted about a question about siphoning. https://physics.stackexchange.com/q/677102/259268
An 10 meter tall cylinder is sitting in a infinite pool of water. It has supports on the bottom attached to the base of the pool to maintain its vertical position. The top of the cylinder is closed and the bottom is open to the water. The bottom of the cylinder is not exposed to air and is submerged. There is a hose located 1 meter below the top of the cylinder which leads through the wall of the cylinder. The hose entrance is at a higher elevation (~9 m) than the hose exit (~8 m). Currently the hose exit is closed.
Water fills the cylinder and hose combination (the air is released, there is no air in the entire setup, only water). The atmospheric pressure outside the cylinder(and hose) and the properties of water allows for the 10 meter height of the water column. Suddenly the hose exit opens, starting the siphon process. Water drops 8 meters into a water turbine sitting level with the surface of the pool. Beneath the turbine is just an extension of the pool that the cylinder also occupies.
As the water falls from the hose exit, it starts pulling water from the top of the cylinder. The open bottom of the cylinder starts pulling water from the pool. The water goes through the turbine and re-enters the pool. The flow of water through the cylinder is continuous as it can not drain the entire pool of water.
