Hello all.
I'm investigating a little bit about stokes law in order to understand the settling velocity of falling particles and on the net i encountered with 2 different formulas and i simply can't find the reason why they are different. every formula gives me a different answer.
The 2 formulas are :
1. Vt=gd^2(Pp-Pm)/18u -
2. V=2/9*d^2*g*(Pp-Pm)/u -
Any idea why they are different ?
Thanks.
