Hello; I have been toying with the idea of creating an Archimedes pump using PVC and 6 inch drainage pipe. The idea is that by using tubing coiled around a PVC core, and rotating it using torque on PVC collars, as long as the pump is angled correctly, and friction is sufficiently low (the collars would ride on stainless-steel rollers), the physics of the matter would point to a kind of anti-gravity effect; where the water is moved upward by continually changing the inclined plane upon which it rests. The inertia of the water at rest gives way as the cavity holding it lowers, yet the water moves upward through the spiraling effect! There's no water loss as the water is held in a tube, and not between a screw and a channel, as in typical materials-handling and sewage-moving Archimedes pumps; the big boys of the pump business. These are usually open on the top, anyway, and so not really pumps in the strictest sense of the word, but really augers. I want to pit a tubular Archimedes pump against a typical pressure-head pump. Of course, to get readings that would show the Archimedes pump to be an energy-efficiency winner (of course, there's still the matter of capacity to consider, since the pump can only spin so fast without the water adhering to the sides of the pump through centrifugal force), I would need a long enough run to put the pressure pump at a disadvantage through having to lift the entire column of water with each gallon inputted. Am I wasting my time? Please tell me if my anti-gravity statement is the result of a mirage, or something in physics that I cannot see?
