minus-squareGork@lemm.eelinkfedilinkEnglisharrow-up0·10 months agoHow does that siphon work? I would think they would need a pump of some kind, even if it’s just a bunch of Roman workers/slaves turning an Archimedes Screw, to get the water to go uphill.
minus-squareCameronDev@programming.devlinkfedilinkEnglisharrow-up0·10 months agoSame way a fuel siphon works, as long as the opening is below the inlet, and the rest of the tube is full and sealed, the water will flow. https://en.m.wikipedia.org/wiki/Siphon
minus-squarejaybone@lemmy.worldlinkfedilinkEnglisharrow-up0·10 months agoBy why did they even need one here though?
minus-squarewischi@programming.devcakelinkfedilinkEnglisharrow-up0·edit-210 months agoBecause it’s simpler to build siphons through large valleys instead of 100 meter high 10 kilometer long aqueducts.
minus-squareDonjuanme@lemmy.worldlinkfedilinkEnglisharrow-up0·10 months agoBut you have to keep water pressure throughout the length of that tube, how did they do that with their materials?
minus-squarewischi@programming.devcakelinkfedilinkEnglisharrow-up1·6 months agoThere is no additional pressure besides from the height/drop, so unless so have a substantial leak where you lose a lot of water, it “just works”.
