DOM: If the amount of water in the discharge bowl is not a ½ cup, continue turning the screw until you get a ½ cup. The site of the fluid to be moved and the amount of fluid to be moved determine the outer radius of the Archimedes screw (the distance from the center of the core to the outer wall of the hollow cylinder), the length of the tool, and how much the tool has to be tilted (the slope). It is said that Archimedes enjoyed teasing other mathematicians, giving them the answer to a complex question but not helping them to understand how he had worked it out. Pascal law states Pressure applied at any point of a liquid enclosed in a container is transmitted without loss to all other parts of the liquid. Therefore there is no inundation of wildlife or surrounding land and minimal increase in water temperature. Archimedes was behind the understanding of the formula of density. So he designed the Archimedes screw. What other inventions did Archimedes develop? Experiment with how fast you can turn the screw and still move water through the tube.
