To make the plot of the velocity variation along the centerline, adjust the XY plot dialogue box as below (in particular, adjust the plot direction to be along X):

...

To obtain this distance, go to File-Export-Solution Data. Select 'X-coordinate', 'Y-coordinate', and 'Axial Velocity' as values to export. Export them along the centerline, and various X locations (like X=10D) as either an Ascii file to copy into Excel, or as a CFD-Post file. Alternately, use Matlab and this function to read in ASCII files at the specified X locations.

Plotting Y-coordinate approximate locations at which U=U_center/2 gives the half width variation:
