Homework Statement
Hi
I need help with designing an apparatus to test my aim.
Aim: Does the speeding up/slowing down of the rate of flow of water affect its electrical resistance.
I need to create an apparatus in which I can alter the rate of flow of water and test the electrical resistance of that water while it is flowing.
Obviously I will test the resistance of water while stationary but I am yet to devise a way to change the rate of flow and measure it empirically.
The materials I have at my disposal are those of a general high school science lab.
The Attempt at a Solution
I thought that perhaps if water was flowing at a steeper gradient, this might make it flow faster...is this correct.
Also, someone suggested something using a height difference and pressure gradient. I am not enitrely sure what that is. If someone could explain that concept and how it might be applied that would be good too.
Thanks
