Weighing the rust

Hi again

For measuring the rust I think I will measure the pipes with a scale where the lowest numebr on the sclae is 1 gram. However I think think I will need something more prescise that also measures milligrams because then the weights will be more varied and the varibale will be better controlled.

I'm think of measureing the pipes everyweek as well to show the rate of rusting. But I ;m not sure if this will affect the overall results at the end of the 4 weeks.

So far this is my idea.

For my discussion I'll probably add how we try to prevent rust in pipes like the different devices and chemicals used.
