Screens block ventilation ops by HOW MUCH?
Was asked a question the other day and can't find the answer anywhere. Its been driving me crazy that I can't find the answer so I thought I'd thow it out here:
Does anyone know how much that screens in a window will block airflow during ventilation operations? I'm looking for a percentage. For some reason it seems like I've heard 75-80% of the air is blocked by the screen, but I can't verify it anywhere.
Thanks for satisfying my curiosity!
