Fluid statics

  1. Sep 3, 2009 #1
    1. The problem statement, all variables and given/known data
    Prove that P1>Po


    2. Relevant equations
    dp=-rho(g)dy
    integral(Po,P1)dp=-integral(Y2,Y1) rho(g)dy



    3. The attempt at a solution
    dp=-rho(g)dy
    intgrl(Po,P1) dp=-integral(Y2,Y1) rho(g)dy
    Po-P1=-(rho(g))(Y2-Y1)
    Po-P1=(rho(g))(Y1-Y2)
    Y2-Y1-->Y1-Y2<0 defined as -del(y)
    Po-P1=-(rho)(g)(del(y))
    P1-Po=+(rho)(g)(del(y))

    not sure where to proceed or if this proves that P1>Po. Please help.

    Oh and the attached file has a diagram on it.
