Air Flow Rate Through Cowl Vent

Anyone seen tables rating cowl vent air flow? Yes, I am an engineer and understand that there are many variables, including pressure drop across the cabin. Still, I have searched and find it curious that I can seem to find anything. Other passive vent styles, marine and non-marine, but not cowls.

Yes, dorade boxes and screen will make a difference, as will direction and airflow patterns over the deck. Wind only, not connected to a fan (although pressure drop info would still be useful--I can calculated it from that).
