Help with modeling bathroom exhaust airflow
(OP)
I am trying to find a resource to help me model the airflow in a vertical bathroom exhaust stack serviced by a rooftop fan, with seven floors, each with two bathrooms. I am assuming that there is an integral that could be used to describe the rate of flow at each floor, but I am having trouble figuring out how to set it up. Does anyone know of any books, etc. that contain this kind of information? Any help would be appreciated.

If you do and are, this is a simple air friction problem.

You will need a pitot tube and a grille hood and a copy of SMACNA or similar.
You will then measure velocity as instructed in duct cross-section. Flow (cfm) = V (ft/min) X A (ft squared) whan all the rules are applied.
Better to get a guy who does balancing for a living and he'll measure a duct in about a minute. Use a locking duct-mounted balancing damper.
