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).© BrainMass Inc. brainmass.com October 10, 2019, 2:50 am ad1c9bdddf
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 ...
In this solution we consider the svedberg equation for determining the sedimentation velocity given a certain angular momentum. See the questions for more details
