We are Team Shark, a group of Product Design Engineering students and as part of our uni course we've been given the challenge to design and build a water pump. The task is to design and manufacture a pump that could lift 5 litres of water up a height of 600mm in a time of 5 minutes or less. We've decided to make an Archimedes Screw and here's how we're getting on.
Wooden dowel (27mm Diameter)
1mm thick sheet steel
1.5m steel rod (19mm Outer Diameter)
1.25m plastic downpipe (65mm Inner Diameter)
Bracket for downpipe
Gearbox (We used one out of a cheap drill)
