Question

can you state three sources of velocity variations that cause mechanical dispersion in a homogeneous porous medium?

Answer 1

is caused the take in a are Some a more are in which friction be becaule Alles Mechanical dispersion by different flow flow paths wader particles geological medium of the flow paths falter because direct they follow path or because they going through larger pores or through the center of pores water flours faster because less is involved. Other flow pathy slower may they are closer the grain boundaries, thus being exposed to more fiction in in the pore throat, the water different flow paths of the water mechanical dispersion. from that the sources cause wanations homogeneous porous markicum pore grain boundanes and of pores. to water particles. The slowing down particles caure the above we con condute discussions of re mechanical dispersion in that aren throat center
