Homework Help: Problem dealing with curl

  1. Sep 29, 2005 #1
    Calculate the average value of the curl of the fluid for a rectangular path 15 cm by 10 cm, as shown in the figure (see file attachment).

    Va=(10i + 5j)
    Vb = (5i+10j)
    Vc= (5i + 10j)
    Vd = (10i + 5j)

    Could someone help me to get started with this one? Please :smile:

    Maybe give me an example of how to calculate the curl for one side??

    I went to the moderation queue to approve your attachment, but it was not there. :confused:

    Could you try to upload it again?

    If I'm not mistaken, the curl of one side (ex. side A) would be the following:

    [tex]\vec{V_a}\times\nabla=\det{\begin{bmatrix}\mathbf{i} & \mathbf{j} & \mathbf{k} \\ 10 & 5 & 0 \\ \frac{\partial}{\partial x} & \frac{\partial}{\partial y} & \frac{\partial}{\partial z}\end{bmatrix}}=0[/tex]
