Please sketch the variation of skin friction vs. Reynolds number for the Question shown in the ms word file.

(See attached file for full problem description)

Use the log-law in combination with the simple power law expressions to analyse steady turbulent flow about a long cylinder of radius R rotating at angular rate in an infinite fluid. Derive and sketch the variation of skin friction, , vs. Reynolds number, (see attached).

Hint: Take the boundary layer length as equal to the circumference of the cylinder.
