Can you explain how it works

Venturi pump

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...

Tell mi who that Dime como lo haces.

What pressure air pump used for this ?

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

what air pump work 45 m deep ?

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

Follow the human physiology model!

Hi there! Thanks for investing in the experiments and doing instead of just talking. I invented a new engine powered by water alone. It feeds on a primary source like the ocean or a lake. Applications are maritime transportation, clean electricity and clean hydrogen generation among others. The HOW is explained in detail on my new book. Would you be interested in a mutually beneficial cooperation to put these ideas to work in the market? THANKS!

Very very beautiful and very very wonderful job

We want design for making thanks

We want design for making thanks

wow, amazing, that is why I love using airlift

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

عمل ممتاز جدا جدا جدا جدا جدا

че лавочку перекрыли ?

but nothing showing high volumes AND high lift

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?

I belive i will try too i need help.

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.

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.

any body >>>>think<<<< that a higher lift would mean more weight on the floating platform and over power the weight limit of the platform. being as it seems winter season and hypothermia is a real possibility, safety requires low lifts and little water weight on platform. just sayin...

After Three Years where are you at? This video didn't show how your system actually works.

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

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

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

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

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.

if you still read these (not sure, since it was 4 years ago), but what does he mean by "simple pipe with another pipe injected into it?" is there a secondary pipe that we don't see? all I see is a simple pipe with an air hose injected. Was there anything I was missing here?

I call BULLSHIT. There is no proof that the air hose is connected in any way. The video just shows the air being blown at the top of the water.

@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.

"communicating barrels" principal and and the displacement of air

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

Visited your site (buoyancyhydro[dot]com) with intention of learning more about your organisation, activities and researches but all in vain since its berely a single page!

Hello, realy this method produces more energy than needed to produce air ?

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

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.

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?

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.

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

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?

really interesting

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

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 ???????

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?

so to get a better lift above the water level a size reduction would induce the Bernoulli principal where the velocity would have to increase with the corresponding restriction in dia. and the lessening of pressure on the pipe wall?

so is the turbine located below where the air is injected then? or does the mixed air/water flow thru the blades?

not sure what I'm seeing here guys. are you using the flowing mass to spin a turbine rotor? How much torque can you harvest for how much air injected to induce the flow? and can a wave generator produce enough lpm to run this flow? if so then it's brilliant. I realize this is not "free" energy but harvesting whats already there in new and exciting ways. just because we're not doing it already does not mean we should quit trying new things / ways. edison and tesla would be proud

I do not understand something here... If I blew air into a tube that size, wouldn't bubbles of smaller size than the large pipe used just rise un-hindered up the pipe? Or is it the effect of having the volume of air injected to the water rapidly which causes the rise of water? Another question I have is can or will this system lift the water to any significant height ? I imaging as soon as you start trying to lift past a certian point relative to the water depth it would just stop flowing
