How do you fill water into a barrel using a hose and barrel that are airtight?

>> No.2623908

>>2623906
Entry point from top and low flow rate so it can pull air from the filling hose

>>2623908
why would the hose have air?

Because you put an ventilation anti vacuum valve before the hose.

Two hoses: one for water, the other for the air

You pump out the air. The water will replace it.

>How
Practically speaking?
Fit the hose to the vessel as normal.
Feed a thinner hose through the real hose.
Rotate the barrel so that the outlet is highest.
Feed water into the barrel through the narrower hose by pushing it.
Or drawing the air out of the larger, thereby sucking in water through the narrower.

Use an air vent with a check valve.

You need a spot for the air to go, ideally on top of the liquid you're dispensing. If it's airtight the whole way through, you'll need two hoses; no other way about it. Pic related will keep pressure equilibrated while gravity dispenses the liquid. If it's flammable or reactive I recommend a nitrogen or argon sweep, as well as grounding all containers.
Also, this is a stupid question/questions that don't deserve their own thread kinda post. Post more ladybots now.

lol you have just transferred the problem to another tank that doesn't have the airtight issue
