Comparable volumetric flow in different sets of holes?

) May 19th, 2014

I am trying to determine the air flow needed in an enclosure. I am running a simulation of floworks (Solidworks) and i have too many holes for the program’s liking. How do I determine a comparable set of holes that are larger and therefore give the program less data to calculate but have a similar volumetric flow rate? Any suggestions?

I would start out with the Engineering calculators that Lee Company
offers for free.
You can calculate the Lohms of one hole and multiply that by 10, for example, and recalculate to get a single equivalent hole. That way you can reduce the number of holes by 10. Of course you can use other numbers.
Lee is a great company and their engineers know their stuff.

I do not own Lee stock nor work there nor have any financial interest in them. I am a customer and think they are wonderful. (You will too.)
