Air solubility in water
Air solubility in water
(OP)
I am looking at designing a siphon pipeline for draining down a reservoir.
As the pressure reduces towards the high point, so the air is released. Are there any tables in literature that specify the air solubility in water at various pressures?
Also, how is the air released at the high point?
Regards
John

Air pressure is sufficient to sustain a liquid height of about 34 feet for water. Above that height, a near-vacuum forms above the liquid in the closed tube. Actually, the pressure there is the vapor pressure of the liquid. At 20°C the vapor pressure of water is 2.3 pascal, or 17.5 mm Hg.
You would need to evacuate the air to start the siphon. Conversely, you may break the siphon by allowing air to enter.
