I still don't see why you can't determine the volume you need by simple
experimentation; you only need enough solution to cover the paper
completely, which should be very easy to determine visually. Forget
"solution height" in mm; just figure out how much liquid it takes to
completely submerge a piece of paper. We're not talking about
high-precision processing here.
