Homework Help: Continuum Mechanics: Check if fluid flow is real

  1. Sep 13, 2011 #1
    1. The problem statement, all variables and given/known data

    see attachment.

    2. Relevant equations

    Navier Stokes continuity equation:


    3. The attempt at a solution

    So what I tried to do was to use the above equation to see if it equals zero.


    then to make the deriving easier I multiplied the density by each of the velocity components


    then I did the derivative part of the equation

    grad.(rho*v)= del(rho*vi)/del(xi)
    =del(rho*vx)/del(x) + del(rho*vy)/del(y) + del(rho*vz)/del(z)

    ^^this isn't zero :/
