I am trying to determine the resuspension rate, Λi (t) , in the i th layer for a multi layer resuspension model. One needs to determine the number of exposed particles , ni (ra',t), in the ith layer to determine the resuspension rate. I am kind of stuck here. I would greatly appreciate the help. I am attaching the file (Check the last page). If you feel any parameter is missing, fill in an arbitrary value.
You forgot to mention what version of Mathcad Prime do you use.
