Indeed, however I was wondering if anyone knew where the equation originally came from (or whether it was simply devised by the website linked in that thread).
I've heard something about it being derived by someone called Faxen?
I was doing some research into my coursework (don't worry, this isn't a real 'help!' thread) on Stokes law, and I found this equation on this forum (posted in 2010), regarding the effect of the walls of a pipe on the calculated value for viscosity when a sphere is dropped through that pipe...
Homework Statement
Hi there.
For my A2 physics coursework I have been doing an experiment into stokes law, in which I dropped ball bearings of various diameters into a tube filled with a liquid, worked out their terminal velocities and then used Stokes Law to calculate the viscosity of the...
