I have a vague recollection of a friend & colleague who did work on Navy subs (quiet!, quiet!, QUIET!!!) showing me a book on noise and noise reduction by one of the eponymous founders of BBN - Mr. Bolt, Mr. Beranek or Mr. Newman. The book was concerned with noise reduction, but addressed sound pressure and power levels and scaling relationships for similar phenomena.
Now, after starting this post I have briefly searched thru Goooooogle, and found two titles from the BBN guys, with these two links:
Noise & Vibration Control Engineering (etc)
You might find these to be useful. I suspect that it is a highly uncertain proposition to calculate noise from first principles, but much easier to scale noise for different flows, pipes size, etc from a "baseline" measurement.
