Hello, again; I thought some more, and figured that the amount of water on the low side of the central axis could be very small, given that pump is made from round tubing and the bend, or curve, of the tubing is symmetrical around a rigid round part, or the PVC central pipe. I don't see where...

Yes, and that would give the operator great arm strength. However, I was really looking at a way to frame the Archimedes pump so that a big wheel, like a bicycle wheel or bigger, could be placed around it at about five feet above the ground, and this would be turned by a belt coming off of a...

Thank you both! This is great thinking; much better than what I could find on an Engineers' forum under Ag Engineering. Oh, well; the best minds will be taken by the hardest subjects, and really I only just started Math for Math Majors and Engineers before quitting college. I almost side-swiped...

Is that really you, sitting on the edge of a cliff? Wow! Yes, the picture of the conventional pump is correct. If no pressure is applied to the crank, and water can flow in at the top, it will turn like an engine. I'm not talking perpetual motion; just conservation of energy. My idea is for...

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...
