Is there a way to calculate the size needed for an intake vent based on CFM's of the exhaust fans? I have an 8'x2'x8' closet with a fan with a 220 CFM rating. using mylar lined shower curtain and other mylar to seal opening and while its not a problem yet, the curtain sucks in a bit much for when they get taller. no real heat issues. I have an idea of material and placement just need to figure out the size so i dont try multiple times.

Any help?
