| Item | Formula / Note | Source / Standard |
|---|---|---|
| Siphon principle | A siphon is driven by atmospheric pressure and elevation difference, described by the Bernoulli equation | Bernoulli D., Hydrodynamica (1738) |
| Atmospheric pressure head | A standard atmosphere of 101.325 kPa equals about 10.33 m of water | ISO 2533:1975, Standard atmospheres |
| Maximum siphon height | Limited by local atmospheric pressure, vapour pressure, velocity head and losses | Bernoulli equation together with vapour pressure data |
| Effect of vapour pressure | Higher water temperature raises the vapour pressure and lowers the available siphon height | ISO 2533:1975 with saturated vapour pressure tables |
