Homework Statement
You are required to pump water out of a very deep mine. Where should you put the pump? Explain your answer fully.
Homework Equations
Not sure
The Attempt at a Solution
See a similar question I did regarding beer in a can, I explained, but I needed formulas apparently, and didn't get marks for my 'waffle' (which is strange because in A level, waffle = good)
So for this question, i feel that equations are neede, but I am not sure what equations will be useful. This question I feel is a fluid dynamics question. So I first thought of Benouilles Equation, but I don't think this is useful, since we don't know the speed the water is travelling.
I also feel I need to use F = mg somewhere, but this doesn't help me.
Could anyone recommend some equations or laws that might be useful?
