Pump with no moving parts! Hi! I'm trying to build a "pump" pushing water a few meters up of the river bank, and wondered if I could do it without ANY moving parts (except water ). My plan is to mount a tube (say 50cm in diameter) with one end sealed into a wide river. The open end of the tube will be facing up-river into the stream. The river floats at approximately 1 m/sec towards (and around) the tube. Now, if I mount a small hose to the sealed end of the tube, how high above the water level can I expect the level of water to rise in the hose (IE how much pressure is in the tube)? To simplify: Hose cross-section = 10 cm^2 (3.57 cm diameter) Tube diameter = 50cm (~2000 cm^2) Tube length = 1 meter (don't think it matters) River flow velocity = 1 meter / second I guess we can simplify by disregarding water viscosity and vortexes. Right? Any help is appreciated!
