Archimedes' Screw

About

Archimedes' Screw is an ancient hydraulic machine credited to the Greek mathematician Archimedes, though its origins trace back to Egypt and possibly Assyria. It consists of a screw-shaped surface inside a hollow pipe, used to lift water from a lower source to a higher level. The screw is typically turned by manual labor, windmills, or engines, making it a versatile tool for irrigation and water management. Today, Archimedes' Screw is used in wastewater treatment and for draining low-lying areas. It can also operate in reverse as a hydroelectric generator, suitable for low-head sites. Its simplicity and efficiency make it a valuable technology in modern applications, demonstrating advanced engineering skills from ancient times. The screw's design allows it to handle varying flow rates and dirty water, making it ideal for diverse environments.
