Nano Airlift Pump Challenge! BEAT THIS to be Champion! And World record holder!

My video http://www.youtube.com/watch?v=6_88_xUd5Zs contains the current record (18 ft high) on Jan 14th 2012 I believe it can easily be beaten. But wash out your tubes beforehand, maybe even put dirt through them! (New tubes have some sort of coating that repels water and makes the experiment more difficult than it needs to be).
The 2011 record was 16 ft high using the conditions in the experiment.
Believe it or not, nobody knows how high this can pump! (updated, December 2011 : Windowfarms suggest that these types of pumps can pump about 10 times the submergence) 25 ft but they do not know for sure.
This is a cheap experiment in open source product development!
Use a little aquarium air pump to pump water to amazing heights with the plug flow airlift process. (I think the best tube sizes are 1'4 inch or 3/16 inch diameter.) so 4 to 6 mm internal diameter How high can you pump? You tell me! (With ordinary airlift pumps, your well needs to be at least 60 ft deep to airlift from 40 ft, with this one it only needs to be 43 ft deep to do the same thing! If you have a suitable place, (maybe you live in a highrise)? or if you have a friend who might do the experiment ,Please expand human knowlege by either doing this simple cheap experiment or at very least passing the link to someone who might try it.
itsandbits1 on instructables dot com pumped to 16 ft high with a similar set up around 12th july 2011. This might mean that a boy or girl in Africa can pump water from a 40 ft deep well using only a bundle of tubes and a small bellows or foot operated air pump!

Thanks

Thank you for the vid. You talked about the hoses having resistance. Can you speak to that, what you did about it or what type of hose you used. Thanks. D

@papadyal1149 I bought blue airline tubes that are made of silicone rubber. They almost totally refused to work! Even water coming down! the tube hardly moved when I turned off the airlift and opened the bottom to clear the "slugs of water" in the tube! I think the normal plastic clear tubes (from hardware stores or winemaker stores) somewhere between 7 mm and 3 mm would be ideal to bring the water up. I think about 5 mm is very close to "perfect" but this awaits experimental confirmation

I would wonder if the distinction needs to be made between air lift and capillary flow.

If anybody gets over thirty feet I definitely want to be informed (old time farm well pump limit is 32?).

[gaiatechnician]

@KWAZAI It isn't like capillary flow, (as far as I know). It is more the distinction between plug flow, churn flow and bubble flow. The physics of each type is very different but way back, 50 or 60 years ago when they wrote the books, people only tested with bubble flow.

If you search for "2 phase flow regime" and look under images, you will see lots of examples. These types of search results did not even exist a few years ago so it was really tough getting people to believe me.

I want this video on my 225 unit.

Very helpful diagram, thank you!!

[virlusun]

I am making another and easier pulser type thanks to this video!

[virlusun]

try to make it as close as I can the original model bc plants do a lot better when water is oxigenated

[virlusun]

sorry but I got a new android phone...so.i

[virlusun]

got is with three outlets. The trupm

[virlusun]

I am working on it. I just finished posting the biofuel pump video. The best results I'v

[KWAZAI]

@gaiatechnician I know what you mean. The best results I've seen are whats referred to as slug flow. I ran across info on bubble plumes about the bubbles reaching terminal velocity at about three story height (free flow bubbles), so that may be the limiting factor. your video of the nano pump and was impressed got me thinking about the capillary flow as a way to get one to pump further.
