Homework Help: Sedimentation time

  1. May 2, 2009 #1
    Is it possible to increase the sedimentation velocity of silica particles (2 um diameter )in water?

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

    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?
