Homework Help: Fluids Homework Problem

  1. Jan 13, 2012 #1
    1. The problem statement, all variables and given/known data

    Let R, L, C, K be suitable dimensional constants. In a certain motion of a fluid,
    the mass density function ρ is given in the Eulerian description by ρ = R*(x1^2+L^2).

    Is the velocity field v1 = C/(R*(x1^2+L^2)) e1 a possible velocity field?

    Is v2 = K*exp(-x1/L) e1 a possible velocity field

    2. Relevant equations



    3. The attempt at a solution

    I was thinking it had something to do with either the conservation of mass or conservation of linear momentum. Am I on the right track or am I going the wrong way?
