ASCE Journal of Hydraulic Engineering Volume 126, Number 1, January 2000, pp. 72-80 THE TURN OF THE SCREW: OPTIMAL DESIGN OF AN ARCHIMEDES SCREW. By Chris Rorres ABSTRACT: The geometry of an Archimedes screw is governed by certain external parameters (its outer radius, length, and slope) and certain internal parameters (its inner radius, number of blades, and the pitch of the blades).

Archimedes' screw, also known as the water screw, screw pump or Egyptian screw, is a machine used for transferring water from a low-lying body of water into irrigation ditches. Water is pumped by turning a screw-shaped surface inside a pipe. Archimedes screws are also used for materials such as powders and grains.

200 B.C.E. , which when twisted inside a cylinder, raises water from a lower level to a higher level, allowing irrigation of fields. The Archimedes Screw is an invention that revolutionized irrigation and water removal. It was invented by Archimedes in the third century B.C. The device was made up of a large screw enclosed in a cylindrical pipe. It is set at about a 45 degree angle. Further, archimedes screw come in different types, based on where they are to be used or planted.

An Archimedes' screw is a type of pump which lifts water up when it is turned. Used since ancient times it lifts water from a lower to a higher level e.g. in rivers or lakes and can be used to irrigate fields or for draining water out of mines. The lowest portion of the screw dips into the water, and as it turns water is scooped up into the tube.
