One of the oldest known ways of transporting liquids and viscous fluids from low to high areas is the well-known Archimedes screw. This mechanism manages to use concepts of hydraulics and fluid transport to be able to carry out the work that water pumps do today. In this article, we will look at how to make an Archimedean screw It can be used to conduct experiments in fluid handling, present it as a science project, or modify it for use as a pumping system for water or other fluids.
- A shaft, which can be made of wood or metal, preferably with a crank.
- 1 plastic bottle.
- 1 plastic tube (hose).
- 2 containers.
Assembling our Archimedean screw
The first step in building our Archimedean screwThe first step is to take the plastic bottle and fix the shaft we have at hand inside it. It is advisable that it is a narrow bottle in which the axle is practically fixed, so that we can create a kind of protective cover over the axle to prevent it from rotting or rusting.
If the axle has a handle, all the better. If it doesn't, we can create a kind of lever by fixing a couple of pieces of ice-cream sticks or wooden strips, making the cylinder rotate on its axis.
Now, it's time to glue the hose (laboratory type plastic tube) with the help of an extra strong glue around the newly created cylinder from the base to the vicinity of the crank. In this way, we can create a kind of screw-like groove.
Our worm screw is now ready, it is time to test it. To do this, we fill a container with water and place the base of the Archimedes screw inside this container. Once this is done, we place an empty container at a height where the top of the cylinder can reach at an inclination. Now, we must move the crank and we will be able to see how the water rises through the interior of the hose to the empty container.
