Archimedes' Screw

This is a scale model of a machine also called an Archimedean screw or screwpump, used for transporting water upwards, for example to drain mines or feed irrigation systems. Its invention is commonly attributed to the Greek Archimedes during his visit to Egypt. The device consists of a screw inside a hollow pipe. The screw can be turned by wind power or some other force. As the tube turns, it scoops up a volume of water, which slides upward and pours out from the top. The model is one of a series showing methods of water power and displacement used in teaching at University College, Dundee.
