I want to ask the (2) question in 8. Thank you!

(iii)Calculate the cirçulation of this velocity field around the path illustrated here:
(1, 1)
X
(-1, -1)
Do this both by the appropriate line integration, and through application of Stokes' theorem.
8. Now consider the steady velocity profile:
by
bx
u =
V =
x +y-
x* + y
which also has circular streamlines.
(i) Calculate the vorticity vector for this flow.
(ii) Calculate the circulation around the same path described in 7(iii), by performing a line
integration. In light of Stokes' theorem, there may be an apparent contradiction between
your results in parts (i) and (ii). Can you think of how this contradiction might be
resolved?
