Hey all, this isnt exactly a DIY project but a concept question.
How much water pushing power can be expected from air pumps? In the last contest green wiki uses air to pump water through his bamboo stalks and whisper has internal filters that use air to push water through filtermedia. My question is, how high can air be expected to push this water and how can that rate be controlled, ie increased height, flow, etc. I am wondering if the air can push water high above the waterline (yes its a waterfall related question but not for my DIY project) or if the water will just end up going around the bubbles and fall back down to the waterline.
Im not sure if this is the correct way to illustrate my question, does anyone understand what im asking?
