Talk:Perrin friction factors

why is the axis ratio defined as rho in the top part of the article, and never appears again later on? it seems to get replaced by p later on. is this a notation mistake? —The preceding unsigned comment was added by 18.79.4.203  (talk • contribs) 17:00, 9 November 2006   (UTC)


 * Oops! Yes, that would be T.S. (Titanic StupidityTM) on my part &mdash; I was probably waffling about what symbol I wanted to use, and lost track as I was writing. Thanks for catching that after all these months!  By the way, please consider becoming a Wikipedian yourself (the link at the upper right); it's fun!  Willow 11:07, 13 November 2006 (UTC)

For the translational friction factor--does it not depend on the direction of motion for the non-spherical cases? Are the results given for motion along the direction of the long axis?63.226.222.211 (talk) 06:24, 24 March 2012 (UTC)
