Can anybody tell me where could I get some information about Roark Method to calculate restriction orifice thickness? I'm looking for a free online book if possible, but I also read that ASME 3-31-3 is also applied for those calculations.

The formula is in a book that you can purchase:

or go to a library and borrow the book:
