    Is there an example of how you solved iteratively in the end ?

      No, but it's rather straightforward if you know some programming e.g. matlab, Fortran, Python or similar. Rearrange the euqation to form the residuals, e.g. write a function that use guesses of Cm and J and your values of ∆P etc to calculate residuals that should be zero, e.g.
      dPi= function of Cm
      … etc
      res(1)=J-(dP-dPi)/mu/Rm
      res(2)=J-k*log((Cm-Cb)/(Cb-Cp)
      and use standard routines for searching for zeros
      It's very similar to what's done (in matlab) in this video on evaporation (using different equations, but still, the principle is the same):

      Doing the iteration by hand is a pain

      I will use comsol to simulate nanofilters, what is your advice?

    what model would you advise I use for a flat sheet cellulose acetate membrane that is to adsorb dissolved CO2 in seawater?
