blood separation
 
Does anybody know how to model the seperation of blood into erythrocite and serum in a centrifuge or where I can get information about this?

I'm curious, how large are blood cells?

Also what exactly is erythrocite and serum in layman's terms..:)

Blood consists of about 50-weight% erytrocite ...particles which are about 5 - 10 microns big, the other 50-weigth% are serum or water with a particle diameter very much smaller than that of erythrocite. The densities are almost the same, something like 1.02g/cm^3 for serum mixed with water and 1.09 g/cm^3 for erythrocite.

Hi,

all I heared about blood flows is that friction is not proportianal grad(v). I heared that from someone who had conducted experiments many years ago. Hope that helps.
