SUMMARY

The discussion focuses on methods to increase the sedimentation velocity of 2 µm silica particles in water, utilizing the equation v = (2/9 η)R_s²(ρ_silica - ρ_water)g. Three primary methods are proposed: two involve adding substances to the water, while the third method does not require any additives. The conversation emphasizes the need for clarity regarding any limitations on the proposed methods to enhance sedimentation velocity.

PREREQUISITES

Is it possible to increase the sedimentation velocity of silica particles (2 um diameter )in water?

[tex] v = \frac{2}{9 \eta}R_s^2(\rho_{silica} - \rho_{water})g[/tex]

Just looking at the equation I can think of at least three methods - two require adding something to water, third doesn't.

I think your question is a little bit too vague - are there any limitations to what we can/can not do?
