Gravity flow Full bore flow
2/3 air
1/3 water water
Gravity flow vs. Full bore flow
Conceptually, if air can be removed,
you need only 1/3 of the conventional pipe size
to drain the same amount of water….

Full Bore Flow
Siphonic action can be observed when we drain water from a fish tank. A pipe or hose filled with water is used, with one end dipped into the water in the tank, and the other end discharging at a lower level.
Principle of Siphonic
