What value, in general/typically would you class as being much less than one?
I am just working some things out with creeping flow, but I just need to see what velocities for my particles give Reynolds number of much less than one. Re << 1 For stokes flow and therefore stokes drag (6*pi*mu*R*v). But what do you actually class as being much less than 1? is 0.01 much less than 1?
basically determining when I need to use the usual drag equation (+skin friction) and when to use stokes.
