The Archimedes' screw, also known as the Archimedean screw, hydrodynamic screw, water screw or Egyptian screw, [1] is one of the earliest documented hydraulic machines. It was so-named after the Greek mathematician Archimedes who first described it around 234 BC, although the device had been developed in Egypt earlier in the century. [ 2 ]
A screw turbine at a small hydro power plant in Goryn, Poland. The Archimedean screw is an ancient invention, attributed to Archimedes of Syracuse (287–212 BC.), and commonly used to raise water from a watercourse for irrigation purposes.
Archimedes is a genus of fenestrate bryozoans with a calcified skeleton of a delicate spiral-shaped mesh that was thickened near the axis into a massive corkscrew-shaped central structure. The most common remains are fragments of the mesh that are detached from the central structure, and these may not be identified other than by association ...
Cicero Discovering the Tomb of Archimedes (1805) by Benjamin West. Archimedes was born c. 287 BC in the seaport city of Syracuse, Sicily, at that time a self-governing colony in Magna Graecia. The date of birth is based on a statement by the Byzantine Greek scholar John Tzetzes that Archimedes lived for 75 years before his death in 212 BC. [8]
Archimedes wrote the earliest theoretical study of the screw as a machine, [13] and is considered to have introduced the screw in Ancient Greece. [9] [14] By the first century BC, the screw was used in the form of the screw press and the Archimedes' screw. [10]
For his 2022 science project, Sener recreated the Archimedes screw, a device for raising and moving water. But he didn’t stop there. But he didn’t stop there.
The first type of screw conveyor was the Archimedes' screw, used since ancient times to pump irrigation water. [1] They usually consist of a trough or tube containing either a spiral blade coiled around a shaft, driven at one end and held at the other, or a "shaftless spiral", driven at one end and free at the other. The rate of volume transfer ...
