I can help. Open your college fluid flow text to the chapter on compressible flow. Find the section on orifices, and apply the methodology.

OR

Use the search functionality on this site and find hundreds of posts on orifices.

OR

Go to the FAQs in this particular forum and find one that deals with orifices.

OR

Search the

http://www for

orifices or "sizing orifices" using your favorite search engine. Mine is Google and Bing.

Good luck,

Which is one of those handy references that you should probably own anyways (and no I dont work for them)
