#### Solution Preview

Please see the attached file.

You should have all the formulae in your book(s) or lecture notes, however, just in case, you can also found the formula for the potential flow round a cylinder with circulation on web page

As required by Brainmass I also past here the contents of the plain TEX source, however you do not have to read it as you have the pdf ...

#### Solution Summary

It is shown that the drag force is zero for a uniform flow past a cylinder with circulation. The solution is detailed and well presented.
