Homework Help: Solving SV(z) = ∫ ρ(z)gdz ~ ρgz

  1. Apr 9, 2015 #1
    1. The problem statement, all variables and given/known data
    I just need to use this formula and then apply p = density and I z= depth

    2. Relevant equations

    SV(z) = ∫ ρ(z)gdz ~ ρgz

    3. The attempt at a solution
    (ρ(z)(z)g))/2 and if ~ ρgz is multiple it would be (ρ(z)(z)g))/2 * ρgz which is (ρ(ρ)(z)(z)(z)g(g)))/2

    Thanks for your help in advance,

    Also not sure what ~ means in this instance??

    Is there a question here?

    This whole post is incredibly vague.

    I agree with post 2, you are not making much sense.
    However, the ~ sign means "approximately equal to". If ρ is substantially constant over the range of z then it can be taken out of the integral sign and you get ρgz.
