  2. Siphon - Wikipedia

    en.wikipedia.org/wiki/Siphon

    Siphon principle In the flying-droplet siphon, surface tension pulls the stream of liquid into separate droplets inside of a sealed air-filled chamber, preventing the liquid going down from having contact with the liquid going up, and thereby preventing liquid tensile strength from pulling the liquid up.

  3. Heron's fountain - Wikipedia

    en.wikipedia.org/wiki/Heron's_fountain

    Heron's fountain is not a perpetual motion machine. [2] If the nozzle of the spout is narrow, it may play for several minutes, but it eventually comes to a stop. The water coming out of the tube may go higher than the level in any container, but the net flow of water is downward.

  4. Jiggle syphon - Wikipedia

    en.wikipedia.org/wiki/Jiggle_syphon

    A jiggle syphon (or siphon) is the combination of a syphon pipe and a simple priming pump that uses mechanical shaking action to pump enough liquid up the pipe to reach the highest point, and thus start the syphoning action.

    The siphon is a simple instrument; but the forcing-pump is a complicated invention, which could scarcely have been expected in the infancy of hydraulics. It was probably suggested to Ctesibius by the Egyptian wheel or Noria , which was common at that time, and which was a kind of chain pump, consisting of a number of earthen pots carried round ...

  6. Archimedes' screw - Wikipedia

    en.wikipedia.org/wiki/Archimedes'_screw

    The screw pump is the oldest positive displacement pump. [1] The first records of a water screw, or screw pump, date back to Hellenistic Egypt before the 3rd century BC. [1] [3] The Egyptian screw, used to lift water from the Nile, was composed of tubes wound round a cylinder; as the entire unit rotates, water is lifted within the spiral tube to the higher elevation.

  7. Ctesibius - Wikipedia

    en.wikipedia.org/wiki/Ctesibius

    Ctesibius described one of the first force pumps for producing a jet of water, or for lifting water from wells. Examples have been found at various Roman sites, such as at Silchester in Britain. The principle of the siphon has also been attributed to him. Hydraulic clock of Ctesibius, reconstruction at the Technological Museum of Thessaloniki
