Oldest Archimedes Screw Ever Found
The oldest known Archimedes screw was discovered at the ancient city of Seleucia, near Baghdad, Iraq. Dating back to the 3rd century BC, this artifact provides tangible evidence of the early use of this ingenious water-lifting mechanism. The design of the screw consists of a helical surface wrapped around a central shaft, allowing water to be raised when the device is turned.
When Was Archimedes Screw Invented
The invention of the Archimedes screw is attributed to the renowned ancient Greek mathematician, physicist, engineer, and inventor Archimedes of Syracuse. While the exact date of its invention is not known, historical records suggest that Archimedes developed the screw in the 3rd century BC. The device was primarily used for irrigation purposes, lifting water from lower levels to higher elevations.
Archimedes Screw Used Today
Despite its ancient origins, the Archimedes screw continues to be used in various applications today. Modern versions of the screw are employed in industries such as agriculture, wastewater treatment, aquaculture, and renewable energy. The efficiency and simplicity of the Archimedes screw make it a versatile and reliable tool for water management and transportation.
Archimedes Screw How It Works
The operation of an Archimedes screw is based on the principle of transferring fluid by rotating a helical surface within a cylindrical casing. As the screw turns, water is trapped between the threads and pushed upwards along the spiral path. The gradual incline of the screw allows water to be lifted to a higher elevation with each revolution, making it an efficient method for moving water against gravity.
What Does Archimedes Screw Do
The primary function of an Archimedes screw is to lift and transport water or other fluids from a lower to a higher level. This makes it an essential tool for irrigation systems, drainage systems, pumping stations, and water treatment facilities. The screw's simple yet effective design enables it to move large volumes of water with minimal energy input, making it a cost-effective solution for various water management tasks.

Archimedes Screw Explained
The Archimedes screw operates on the principle of displacement, where the rotating helical surface displaces water along the spiral path. As the screw turns, water is trapped and pushed upwards, creating a continuous flow of fluid. The gradual pitch of the screw ensures that water is lifted efficiently without causing excessive turbulence or energy loss. This simple yet effective mechanism has stood the test of time and remains a valuable tool for water management applications.
