Also the length of the stem is NOT equal to the height of the hookah.
Ding ding, winner. Was just talking this over with a friend on aim actually.

You'd have to measure the air volume at any given time across each choke point, bowl, stem, diffuser, hose port, hose, hose tip, and add them cumulatively, and the density of the smoke factors in as well.
