The Archimedes' screw, also known as the Archimedean screw, hydrodynamic screw, water screw, or Egyptian screw, is one of the earliest hydraulic machines named after the Greek mathematician Archimedes who first described it around the 3rd century BC. This simple yet effective device has been used for centuries to lift water from lower levels to higher levels, and it continues to find applications in various industries today. One of the common uses of the Archimedes screw is in pumping water from boats, providing an efficient and reliable method for water transportation and drainage.
As a machine used for lifting water from a low-lying body of water into irrigation ditches, water is lifted by turning a screw-shaped surface inside a pipe. In the modern world, Archimedes screw pumps are widely used in wastewater treatment plants and for dewatering low-lying regions. See more
Oldest Archimedes Screw Ever Found
The oldest known Archimedes screw was discovered in the ancient city of Hama in Syria and dates back to the 3rd century BC. This archaeological find provides evidence of the early use of this innovative technology in ancient civilizations. The design and principles of the Archimedes screw have stood the test of time, showcasing its enduring relevance and practicality.
When Was Archimedes Screw Invented?
The Archimedes screw is believed to have been invented by Archimedes himself in the 3rd century BC. Archimedes, known for his contributions to mathematics, physics, and engineering, described the screw as a means of lifting water for irrigation purposes. The invention of the Archimedes screw marked a significant advancement in hydraulic engineering and has since been used in various applications across different industries.
Archimedes Screw Used Today
In modern times, the Archimedes screw continues to be utilized in a wide range of applications, including agriculture, wastewater treatment, aquaculture, and energy generation. Its simplicity, reliability, and efficiency make it a popular choice for pumping and lifting water in both industrial and domestic settings. The versatility of the Archimedes screw ensures its continued relevance in contemporary engineering practices.
Archimedes Screw How It Works
The operation of the Archimedes screw is based on the principle of a rotating helical surface inside a hollow pipe. As the screw turns, water is trapped between the flights of the helix and is pushed upward along the length of the screw. The upward movement of the water allows it to be lifted to a higher elevation, making it ideal for applications where water needs to be transferred vertically. The rotational motion of the screw creates a continuous flow of water, making it an efficient method for pumping.
What Does Archimedes Screw Do?
The primary function of the Archimedes screw is to lift and transport water from lower levels to higher levels. This makes it an essential tool for irrigation, drainage, flood control, and water supply systems. In addition to its use in water pumping, the Archimedes screw can also be employed in conveying granular materials such as grain, sand, or seeds in industrial processes. Its ability to move materials efficiently and continuously has made it a valuable asset in various industries.
Archimedes Screw Pump Data Table

| Parameter | Value |
|------------------------|------------------------|
| Screw Diameter | 0.5 meters |
| Length of Screw | 3 meters |
| Pitch of Screw | 0.2 meters |
| Rotation Speed | 60 RPM |
| Flow Rate | 500 liters per minute |
| Power Consumption | 2 kW |
Archimedes Screw Explained
The Archimedes screw consists of a helical surface wrapped around a central shaft, forming a spiral structure resembling a screw. When the screw is rotated, the helical surface traps water or other fluids and solids, causing them to move along the length of the screw. The upward movement of the material allows for lifting or pumping action, making it an effective method for transferring substances from one location to another. The simplicity and efficiency of the Archimedes screw have made it a timeless invention with enduring practical applications.

Before you replace the whole screen, try the cable that attaches the frame to the back of the screen. My bike+ arrived with a screen that didn’t work and I was in an absolute panic because I lived outside of a peloton region and had gone to great lengths to get a bike, but I read this tip somewhere online and bought $10 usb c to usb c cable on Amazon which worked perfectly.
