Water pump question

  1. Nov 28, 2008 #1
    1. The problem statement, all variables and given/known data

    You are required to pump water out of a very deep mine. Where should you put the pump?

    2. Relevant equations


    3. The attempt at a solution

    I am sure that this is a very easy problem but I can't see mathematically how to solve it. I know that if the resevoir of water at the bottom was under atmosperic pressure a suction pump could only raise the water about 10 meters and therefore not be useful. So, you would use a forcing pump below the column of water but how do I work out where exactly it goes?

    What level is this question (are you in mining engineering college?)
    I suspect it just wants you to know that you can't 'suck' water more than 10m - which you have done, and so you would have to pu tit at the bottom.

    I suppose for extra credit you could put it 10m up from the bottom!
