A water tower is filled with fresh water to a depth of 6.38 m. What is the water pressure at a depth of 3.96 m?

  • Physics -

    take a column of area A, height h.

    The weight of that column is density*volume*g=density*Ah*g
    = 1000kg/m^2*9.8N/kg*A*(3.96)

    pressure= weight/A

    I measured depth from the top, I assume the writer here had that in mind.

  • Physics -

    I'm confused about what A should be then? Is that what I'm solving for? I thought I was solving for pressure?

  • Physics -

    A cancels top and bottom

  • Physics -

    Top and Bottom??
