Ideal fluid problem

  1. Feb 15, 2012 #1
    1. The problem statement, all variables and given/known data
    An aneurysm is an abnormal enlargement of a blood vessel such as the aorta.
    Suppose that, because of an aneurysm, the cross-sectional area A1 of the aorta
    increases to a value A2 = 1,7A1. The speed of blood, with average density of
    1060 kg/m3, through a normal portion of the aorta is v1 = 0,40 m/s, and through
    the enlarged region is v2 = 0,24 m/s. Using the model of an ideal fluid and
    assuming that aorta is horizontal (the person is lying down), determine the
    amount by which the pressure P2 in the enlarged region exceeds the pressure
    P1 in the normal region!

    2. Relevant equations

    3. The attempt at a solution
    The only thing is how to get an equation for pressure from this a1v1=a2v2
    I guess
