Calculating noise level of sonic flow in a pipe
Calculating noise level of sonic flow in a pipe
(OP)
I have a situation where there may be sonic flow of (50 psig saturated) steam in a (2") pipe. This would occur rarely, but it would be useful to be able to estimate the noise level at some distance from the pipe. Can someone please provide the appropriate equation(s) and/or point me toward the correct source/authority for such equations? Thanks.

p(success)~0 but you'd learn a lot.
I'm assuming this is a 'raspberry' noise?

Good suggestion for a starting point: after poking around, I found some graph-based data that allowed a reasonable estimate. At the same time, I also found analytical relations that allow estimation in a spreadsheet. Thanks.
