I have to do an experiment for my english class:
I have to use two or more containers of same size and shape and punch holes in the bottoms of these containers. The holes should vary in size and number for the different containers. Then I have to fill the containers with water, sugar and flour and measure how long it takes for different substances to flow out of the container
Since I am German I have the problem that I am not really sure about the english terms and leo.org is not helping alot...
1.) What scientific principles do I have to consider?
2.) It is pretty easy to find something about hydromechanics, but what about the solid materials?
The Attempt at a Solution
density of the material
diameter of the holes
number of holes
2.) I would use kinetic principles
