Archimedes’ screw
Archimedes’ screw is a machine used for transferring water from a body of water into irrigation ditches. Water is pumped by turning a screw-shaped surface inside a pipe. Some researchers have postulated this as being the device used to irrigate the Hanging Gardens of Babylon, one of the Seven Wonders of the Ancient World.
About Archimedes’ screw in brief
Archimedes’ screw is a machine used for transferring water from a body of water into irrigation ditches. Water is pumped by turning a screw-shaped surface inside a pipe. Although commonly attributed to Archimedes, there is some evidence that the device had been used in Ancient Egypt long before his time. Some researchers have postulated this as being the device used to irrigate the Hanging Gardens of Babylon, one of the Seven Wonders of the Ancient World. The screw was used predominantly for the transport of water to irrigation systems and for dewatering mines or other low-lying areas. It was also used in the successful stabilization of the Tower of Pisa in 2001. Many forms of axial flow pump are found in pescalators, which are designed to lift fish from fish ponds and transport them to another location.
This technology is primarily used at fish hatcheries where it is desirable to minimize the physical handling of fish. An axial pump is essentially an elevator or snow blower or grain elevator. It is basically an Archimede screw basically contain an archimedes flow pump basically contain a flow pump. It’s the oldest positive displacement pump. The first records of a water screw, or screw pump, date back to Hellenistic Egypt before the 3rd century BC. 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 higher elevation.
