Homework Help: Bernoulli's Principle

  1. Apr 19, 2010 #1
    1. The problem statement, all variables and given/known data

    Using these equations:

    1) Vb/Va = (Da/Db)^2
    and
    2) Va^2 = (2(Pa-Pb)) / [density*((Da/Db)^4)-1]

    Derive a mathematical expression for delta(Pa)/delta(Pb) in terms of Da and Db

    2. Relevant equations

    1) Vb/Va = (Da/Db)^2
    2) Va^2 = (2(Pa-Pb)) / [density*((Da/Db)^4)-1]

    3. The attempt at a solution

    No idea where to start.
    Should I solve for Va^2 in equation 1 and sub that into equation 2 and solve for Pa and Pb?
