  1. Jan 19, 2007 #1
    This topic is about streamlines, pathlines and streaklines. Please could you see if you could help me out, only if you answer one of the questions would be a great help. Thanks alot:smile:

    1) When are these line identical??

    2) Is the visualied line a streamline, pathline or a streakline in the following cases.

    a) The stream plume released from a vent pipe at a power plant.

    b) The vapour trail of a jet airplane.

    They are identical in steady flows, i.e the velocity at a point does not change.
