A hollow tube has a disk DD attached to its end (Fig. 16-33). When air of density p is blown through the tube, the disk attracts the card cc. Let the area of the card be A and let v be the average air speed between the card and the disk. Calculate the resultant upward force on CC. Neglect the card's weight; assume that v 0 ≪ v, where v 0 is the air speed in the hollow tube.
