All,

I have a rectangular box of volume v. On the north face is a fan that is forcing air into the box at a mass flow rate of m. On the east and west faces are two outlets of varying areas, say A1 and A2. Is there an easy approximate calculation that will tell me the mass flows out of the two outlets and the average pressure inside the box.

I know this can be done easily by cfd, However, that is not the answer I am looking for.

Thanks.
