Fluid Mechanics: streamlines for a flow

  1. Feb 10, 2008 #1
    1. The problem statement, all variables and given/known data
    Show that the streamlines for a flow whose velocity components are u=c(x^2-y^2) and v=-2cxy, where c is a constant, are given by the equation x^2*y-y^3/3=constant. At which point (points) is the flow parallel to the y axis? At which point (points is the fluid stationary?

    2. Relevant equations

    3. The attempt at a solution

    intergral dy(x^2-y^2)=intergral -2xy dx
    ans y=sqrt(6)x?

    How do i show what point is parallel to y axis and what point is fluid stationary?
