- Let the coordinate axes be walls of a containing vessel for a fluid flow in the first
quadrant that is produced by a source of unit strength located at z 1 = 1 and a sink
of unit strength located at z2 = i. Show that F (z) = log z: -^1 is t he complex
z + l
potential for the flow shown in Figure 11.99.
Figure 11. 99- Let the coordinate axes be walls of a containing vessel for a fluid flow in the first
quadrant that is produced by two sources of equal strength located at the points
z1 = 1 and z2 = i. Find t he complex potential F (z) for the flow in Figure 11.100.
