Homework Help: Question on Bournoulli's Theorem

  1. Nov 15, 2009 #1
    1. The problem statement, all variables and given/known data
    An ideal fluid flows in the tube which constricts and drops. What must h be in order that the pressure in the fluid at the bottom (P2) equals the pressure at the top (P1)? Express h in terms of v1 and g

    2. Relevant equations
    P1 + 1/2pv22 + pgh = P2 + 1/2pv22 + pgh

    3. The attempt at a solution

    Honestly I don't even really know where or how to begin....

    b/c A1 = 1/2 A2
    A2 = A1/2
    therefore, v2= 2v1

    aside from that I don't know how else to proceed..
    Please help
