OT: Calculating ventilation "free area" requirement.

Consider a room that measures 8’ x 10’ x 8’, or 640 cubic feet. I want to install a fan and vents that will exchange the air in this room about once every 2-3 minutes, so a fan should be rated in the range of 210 – 320 cfm.
I need some guidance in how to calculate the appropriate free area of the vent(s) that will allow the fan to pull air from adjoining rooms through this room.
Any suggestions? I expected to be able to find an online “calculator’ for this scenario, but no luck so far.
Thanks
