The Archimedes Screw is a positive displacement pump, which takes fluid from a source and forces it to another location, where it is discharged. The pump consists of an auger (helix) contained within a tight fitting cylinder, and the blades of the helix create individual pockets between the auger and the wall of the cylinder. ...

This paper proposes a simple yet efficient procedure for the design of an Archimedean screw operating as a turbine. The most important formulas proposed in the paper are those for calculating the outer diameter and the rotational speed of the screw. The condition imposed for finding the diameter is the maximization of the torque produced.
