    From the equations in the attached file develop an expression to help answer the following:

    Under the conditions of Fsed=Ffriction and given (1-pv) and w are constant, what physical properties of a particle would influence the sedimentation velocity of that particle moving through a sample cell under the influence of the above centrifugation forces?

    Give examples of changes in these physical properties and how these changes affect the sedimentation velocity v of the particle as well as the s value (sedimentation coefficient).

    I will represent omega with "w." Capital V will be used to represent Vp, p is used as the Greek letter rho, which looks like a p.
    Since the Fsed and Ffriction are equal, we can set equal the components of those equations
    mw^2r-Vpw^2r = vf
    A few different properties immediately present themselves as important. The mass of the sample m and the length of the rotor radius can be varied to achieve different effects. In ...

    Solution Summary

    In this solution we consider the svedberg equation for determining the sedimentation velocity given a certain angular momentum. See the questions for more details
