How do u get water upon an aqueduct? (don't ask...it's a skool project)?
81235
If it's just a school project, you might try pumping it or simply use a bucket. It depends on how large your model and pocket are.\nIn actual aqueducts, the water is already at a higher level (like a mountain spring or lake) so I think it would be fair to replicate that situation.

I've "witched" water before, but it is a questionable method.  I got 2 two foot long bronze brazing wires from a welder, bent them into equal sized "L"s....not everybody can do it, but you can try it over municipal water lines to see if it works for you.  I am a scientific person generally, but it does work...there is something to it.  be careful to hold them lose but level...go back and forth different directions...if you get a hit, try it from a different direction...don't let your sub-conscience mind take over and try to fool you.  there are times for me that I could not stop the crossing of the wires the indication was so strong.  The method is questionable because there is no depth meter on the wires and it could be anything, like differential density of the sub ground causing it...it could be water or something else.  I have heard of "witching" graves because of the differential density I suppose.

1. you need firstly to have a total density equivalent to that of fresh or salt water(for whatever purposed required)\nthen bouyancy will be stable/maintained \nthis will make a suitable start\n2. forge a shape suitable to make the sub hydrodynamic, this will enable the prototype to glige through the water \n3. have fun!

See if you can find a small fountain pump at the local craft store. I found one years ago that fit inside a medium size vase. It was something like $15 or $20. From there, build a river bank around it.

water,but not from the sink...yee..2pts...

Oh yes@!\n\nCheck the article "Scientists make water run uphill " below\n\nand water can also run up hill \n\ncase 1 capillary motion due to surface tension (in plants)\ncase 2 siphon arrangement  \ncase 3 difference in pressure (as in fountain...)\n\nand artificialy\nmay be there is even case 4 if you want to get some polymers involved http://www.stevespangler.com/archives/2006/02/08/water-can-run-uphill/\n\nFor an instace of case 3 check this out http://www.iit.edu/~smile/ph87t2.html \n\nAnd superfluid don't really run uphill http://www.madsci.org/posts/archives/feb98/888462465.Ph.r.html

Ok. this is simple. u need to know about buyoancy, like how air is lighter than water. all you really got do is put some small weights (ex. paper clips, rocks, etc) in the bottle. have it so that it will just barely float. then cut a hole to the side and insert the end of a tube in it. make sure it is water tight. then place it in a tub. it shold float, when you suck on the end of the tube, it should take some of the air out making it less buoyant, and therefore it will sink. there are also many other ways to do this that will make it function more like a real submarine like putting the bottle with weights inside and somehow add pressure to the the outside of the tube to compact the air inside the bottle, causing it to sink. good luck on your project

With only pipes, no motors or whatever, you are only going to be able to use a siphon system, which will only allow you to lift the water if the eventual destination of the water is BELOW the start point.  A siphon won't lift water from the bottom of a well to the top, but in can lift water from one reservoir, over a wall, to a tank below or something like that.  \n\nAlso, bear in mind that suction of any kind can only raise water about 33 feet.  After that, the weight of the water in the pipe will be too much for the suction.  That's why the pump for a well is located at the bottom of a well, so it pushes the water up rather than pulling the water out from the top.  For this reason, a siphon can't work if it has to lift more than 33 feet.\n\nThere is another possibility - a pump based on a fluidyne Stirling engine.  Here's a link or two, you should be able to find more:\nhttp://www.fieldlines.com/story/2004/12/9/41413/0938\nhttp://www.maxpie.de/Fluidyne.htm  (in German, but has great pitures)

water was being taken but not put back!?

step 1: place a bunch of buckets around your school\nstep 2: after a rainy day collect all the water from the buckets.\nstep3: boil the water to kill all the bacteria in it.

Gotta approach this using basic principles.\n\nEnergy is the integral of force applied over a distance.\nTheres two sets of forces working:\nfluid and gravitational.\n\nSo you make your control volume, and look at it.\nYou want to raise the water in it, thats mgh or rho*v*g*h\n\nYou also have to exert a pressure to push against the water ahead of it.  The downward pressure acting on your control volume is f/a so the force you must overcome is p*a and you are traversing distance h so the energy is p*a*h\n\nTherefore to raise the fluid vertically against a down pressure and against gravity the minimum energy (real world is lossy) is \nE = h*(mg+pa)

A waterway is any navigable body of water. These include rivers, lakes, oceans, and canals.\n\nAn aqueduct is an artificial (man-made) channel that is constructed to convey water from one location to another. The word is derived from the Latin aqua, "water," and ducere, "to lead." Many aqueducts are raised above the landscape, resembling bridges rather than rivers. Sufficiently large aqueducts (water bridges) may also be usable by ships. They are similar to viaducts, though they carry water instead of a road or railway. While a road bridge often carries the roadway at a more elevated level than the rest of the road, such a variation of height is not possible for an aqueduct.\n\nreform question
