1M20.37 - Archimedes' Screw

Code Number:
1M20.37
Demo Title:
Archimedes' Screw
Condition:
Excellent
Principle:
Simple Machines
Area of Study:
Mechanics
Equipment:
PVC Archimedes's Screw assembly, long box of colored water, beaker to collect water at the top of the screw, iron ring and clamp.
Procedure:

Clamp the ring to a tall rod and adjust the height so that the screw assembly just clears the near end of the box of colored water.  Place the empty beaker under the screw water outlet.  Turning the assembly counter-clockwise will transfer water from the lower to the higher end of the Archimedes' Screw.
