It is easy to see that in the last two modes of motion the elementarystreams cannot actually extend in a pointed form to the axis or to… … Fig. 2 lines which represent an uniform straight current in an uniformly thicklayer of liquid are simply parallel equidistant straight hues, such as thoseshown in Fig 3. The stream-lines which, in a similar layer, represent acurrent diverging from or converging towards an axis, are straight lines…
