Homework Help: Strange vector/flux question

  1. Feb 5, 2008 #1
    1. The problem statement, all variables and given/known data

    Air is flowing with a speed of 0.4m/s in the direction of the vector (-1, -1, 1). Calculate the volume of air flowing per second through the loop which consists of straight lines joining, in turn, the following (1,1,0), (1,0,0), (0,0,0), (0,1,1), (1,1,1) and (1,1,0).

    2. Relevant equations
    Possibly flux = integral A.n dS if projection is required?

    3. The attempt at a solution

    I've tried doing this by dot producting he velocity vector with the surface area vector of three planes, a square of area 1 in the xy plane, the same in the xz plane and a triangle in the zy plane of area 0.5. However I don't think this is right. Please help!
