Steam jet -- noise level
Steam jet -- noise level
(OP)
When steam under pressure discharges from a vent pipe it creates noise.
Is anyone aware of a way of calculating the likely noise level given the diameter of the pipe and pressure of dicharge?

RE: Steam jet -- noise level
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)
http://www.opengroup.com/tabooks/047/0471617512.shtml
Handbook of Acoustical Measurements and Noise Control, 3rd ed.
http://asa.aip.org/books/handbook.html
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.
RE: Steam jet -- noise level
Thank you for the references. I shall dig out my copy of Noise and Vibration control and see what it says. Again thanks for this useful reminder.
Much appreciated.
