Using Stoke's Law for determination of terminal velocity.
Using Stoke's Law for determination of terminal velocity.
(OP)
Dear sirs,
Now I am working on the project where we are installing a line to transport a water which can contain significant quantity of sand. Main purpose is to size this line diameter small enough to have the actual fluid velocity less that terminal velocity to avoid the sedimentation of sand. Particle size is < 250 micron. Reynolds number in the piping is 90805 ....
I want to use a Stoke's Law for the determination of the terminal velocity, am I right?
Thanks in advance.

Otherwise I think your approach is as correct as it needs to be. You might want to see GPSA Volume 1 Chapter 7 for some basic salient equations.

Katmar is correct; there are better theories and correlations with respect to re-entrainment and saltation. I have not looked at the reference katmar has listed, but another book is suggested by me here:
