Nice flow:-)!! I would like to know if you are using a diffusor to spread the oxygene at the bottom, if you do so...what kind of diffusor? If you use a shorter pipe lets say 17m, how will that effect the flow abowe surface? Do you have some data on that or know where I can get it? Answers will be appreciated! Tore

[@workwithnature]

Well that platform was moving from the water being dumped. If you made the opening a bit narrower you would have quite a lot of speed. For such a small amount of air you could perhaps turn it into a motor?

[@giobelkoicentercom]

wow, amazing, that is why I love using airlift

[@munazirhazar9588]

Dear sir I have 400feet deep bore well and I have only 100feet water present inside borewell (i.e., 300feet below ground level- 300feet has no water only the lowest 100feet has water present) if i use 1/2inch riser pipe and 1/2inch air hose, will I get water at ground.or 1inch riser pipe and 1/2inch air hose. If not kindly suggest some suitable solution...

[@CALOCALKY]

I wonder with a flexible pipe is this the way to pump water from key pieces of infrastructure when their is flooding

[@romandybala]

The lift of this setup is only the height of the lip of the pipe above the level of the water. About 18 inches or so. Whats the big deal? Get it to fill one of those large section pipes at full height above water. Am I missing something here?

[@fletcho11]

what kinda PSI is needed, and what kinda wattage is used compared to a standard pump?

[@prizonfrost123]

20 watt air pump gives you flow rate of 15000 litre per hour, used with 4 inch pipe and 5 inch compression chamber,

[@DEXTER-TV-series]

@@prizonfrost123 How it is maked ?

[@cronos51101]

Think of it is as if everything in the pipe is one mixture. As you add air to this mixture (at the bottom of the pipe), the density of the mixture is reduced. Think of it like Styrofoam. Buoyant forces cause the heavy outside water to lift the column of lighter mixture (air/water in the tube). But because the mix is only so much less dense than the surrounding water, it only produces so much buoyant force. For higher lift, you need more air, but too much and the water just falls out of the air.

[@AircondGypsy]

Thats HUGE, I thought bubble lift was restricted to about 2" line. this reshapes my thinking completely. is there any special way in which the air is introduced into the pipes (some form of distributor fitting ) or does it just get injected at depth and find it's own balance of mix on the way up?

[@TheShakeWels]

Search AIRLIFT.EU there is a step by step guide on constructing the air chamber.

[@naveenkumar7710]

i have a 120 feet well.. can i move water 20 feet above the ground level..

[@PennyPincherCoins]

my question is your only pushing water 1 or 2 feet. When you put the pipe in the water, it will fill the pipe to the lakes water lvl. Can you try this same thing in a water well and see how that works, when the pipe is like 200 feet before it hits water? and only 50 more feet under water? that's a real test

[@dawinksta]

That’s not “a real test” that’s a different application that an airlift might not be best suited for.

[@klflaw]

Being not fully familiar with the balance of atmospheric pressure to the water pressure out of which you are lifting the water, could you kindly explain why the water can not travel higher up the tube than about 1/3 meter above the water line? What is the physics stopping a higher lift?

[@alistairarthur]

I pump live salmon with both 8 inch and 10 inch pipe with 6 or 7 meter depth. We pump to a height of about 8 feet. Do you know the limit of height you can pump? Is there a formula to work out the depth needed to achieve a certain height out of the water?

[@BoBowles]

What air pressure and volume delivered what volume of water through what diameter pipe over what period of time at what depth? Please :)

[@gagandeepsangha]

Dear sir, Could you pls guide me the size of compressor needed in order to get underground water 40 meters under the ground through 3 inches delivery pipe.

[@Jack32720]

but nothing showing high volumes AND high lift

[@mohammadjulhas6417]

Very very beautiful and very very wonderful job

[@AngelLestat2]

I dont understand what is the purpose to test it with long height pipes? They want to know if the friction reduce the flow? The question here is how energy efficient is this vs normal pumps. And how high (about the surface) the water reach (pressure). Also if you want to sent bubbles to a deep of 1000m, you would need a huge air pump, but all those bubbles combines until the surface would create a huge flow.

[@romanmartinez4266]

Tell mi who that Dime como lo haces.

[@trailkeeper]

Nice. I guess its one way to also airate and mix large bodies of water.

[@blogobre]

@jokers32463, with this type of pump the more water pressure [deeper] the better it works as it's the ratio between the depth of the inlet to the head height that matters. Typically the head height is poor, but if you have a deep well it should work great and no need for pumps down the well itself. [Still need the air pump] and will easily bring it down from that depth. Air rises and will rise to the surface. The pumps work mostly because of the air is compressed [less volume] and as it rises it increases it's volume and displaces more water consequently, pushing water to the surface.

[@dustdevil317]

The problem with this pump design, is that it cannot move head height. Regardless of the volumetric efficiency, when you can't lift water much more than 1-2 meters above the surface, you haven't got a pump, all you've really got is an air-powered sluice. What do I do about pumping water from 350-meters below the ground surface? NOTHING. This pump doesn't pump. (and yes, there are MANY wells that are that deep in the Sonoran and Chihuahuan Deserts, alone).

[@hoyofernando]

Dust Devil Commercial divers use the Air lift for dredging, and it works great, as it can handle large volumes of solids, mud and sand. I worked on dredgin projects moving more tan 10,000 m3 of material from the seabed

[@karenmcadie3432]

Fernando Hoyo

[@jamesrollins6315]

Dust Devil again: it's to flip water columns not high headwork pumping

[@mfanto1]

"communicating barrels" principal and and the displacement of air

[@بلاحدودبلاحدود-م7ح]

We want design for making thanks

[@ArchNoob5]

they were testing same airflow yet different diameters of pipe and flow production to the relation in pipe size and length..... does it have more lift than a normal pump no... flow with a short lift? YES..... it would help with gas exchange issues in steady temp areas and help prevent the carbon dioxidw disaster that happened in Africa when the lake burped.

[@mikemachielsen3196]

all you guys with your science i just want to use this one in my pond xd

[@robertogarcia245]

pressure air that I need to draw water from a well that has a mirror 30 meters and a total depth of 60 metros..por please

[@LsFarmar]

what air pump work 45 m deep ?

[@DutchBane]

You can put the airchamber on the last pipe at like 8ft deep and it will still move the water below up through the pipe.

[@scott98390]

you keep adding pipe - but you're only pumping it a couple of feet above the water level.

[@MehmetBoysal]

Scott, that's exactly right.

[@maximonacer5039]

Systole-Diastole, use two times like in the human heart. Use alternating unidirectional valves!

[@MrDieseltwitch]

yay you managed to lift a lot of water an entire foot! Lets see how high it will pump

[@safetyfirstintexas]

any body >>>>think

[@TheBambislayer]

But has no Head Pressure and cannot lift more then 1ft of head at all volumes

[@thedataflo]

oh my fucking god howmuch water comes up there from a bit air letz say u pump it 3 meter higher and let it run to a warer turbine and power the little compressor whit it how much energy is left ???????

[@محمودهلال-ش3غ]

عمل ممتاز جدا جدا جدا جدا جدا

[@dustdevil317]

You guys don't know ANYTHING about hydraulics, obviously. In reality, you are sending 100-foot of casing down into sub-surface waters, and only pumping 2-3 foot of head, which you could do with a Cuisinart blender. Seriously, you aren't lifting but 1-meter of water. Now, go up on those cliffs with all that casing, and pump water up there with only 1-foot of casing submerged. IT WON'T WORK! Air lift cannot push hydraulic head. All you will end up with is a really pretty bubble fountain that you can't see, because your casing is opaque.

[@dlwatib]

It can work better than you think, but you have to have as much pipe below the water as you do above. You can't pump through a 100 foot pipe that's only one foot deep in the water. But you can pump to a height of 50 feet if you put a 100 foot pipe 50 feet in the water. And of course you have to have air pressure at least equal to the water pressure at the bottom of the pipe, so it's no miracle solution by any means.

[@qaz9258]

I understand what you are saying Dust. I am looking for a "Fountain" pump with considerable height. I want to do this with air. But pumps are not limited to head height ability. Like Fernando points out MOVING water is some times the only need. For another example a pool pump. If we apply the wing principle or Bernoulli principal you will realize that the lower pressure within the column is lifted by the greater pressure outside. With that in mind the deeper the column insertion, the higher head. Tapering the column could result in a significant head.

[@jamesrollins6315]

it's to flip the water in a column dust devil, volume for fish management, other kinds of activity when large volumes must be flipped and or aerated.

[@Sugarsail1]

yeah this is stupid, all they're doing is what an aquarium air pump does...aerate and circulate the water.

[@hoyofernando]

Well, air-lift is not for pumping at high level, but large volumes of water. It is used by diversfor dredging large volumes of sand or mud. kzbin.info/www/bejne/l37TY4aNltGkiJI
