For the sake of discussion, I am going to presume that all the retained solution is in the film, ignoring that some of the retained solution is actually on the reel and tank walls. I will also round my figures off where it suits me. I calculated somew time ago that a 36 exposure roll of film on the reel when saturated held some 30ml of solution.
That seems like a very high figure to me. As a very rough calculation, I make the total volume of a film to be (100x2.6x0.05)=13cc. It is probably thinner than 0.05cm (1/2 a millimetre) but definitely no thicker.
Do you mean the volume encompassed by the spiral of the film?
