RE: transit compartment question
Dear Ethan,
I perhaps shall add that time for molecule to transition between two
neighboring compartments is equal to 1/ktr, therefore total time for
molecule to reach the absorption site will be sum of times for n+1
compartments, e.g. (n+1/ktr).

Dear Ethan,
The analytical solution for the transit model is derived for the chain of
n+1 transit compartments. You will notice that the part of analytical
solution is factorial function (n!). If the chain had a length of n transit
compartments, one would need to use factorial for (n-1). This would require
bounding of initial conditions for n (lower boundary at 1). Whichever
approach you use, the outcome shall be the same. Clearly, our preferred
approach is the one we published.
Hope this helps,
Rada

Subject: [NMusers] transit compartment question
Hi all,
I was implementing transit compartment for a absorption model for the
first time. I could not understand why the relationship between mean transit
time and transit rate is MTT=(n+1)/Ktr.
Could someone help me understand?
Thank you.
