Noise of steam through gate valve 1

[jproj]

Can anyone point me in the right direction? I need help in calculating the sound generated from saturated steam (~35 psig) passing through a gate valve and exiting to the atmosphere.

Thanks!!

ANSI/ISA-S75-17-1989 Control Valve Aerodynamic Noise Prediction would be a good place to look.

There also is a section on valve noise in the Noise and Vibration Control Engineering: Principles and Applications by Beranek and Ver. It contains a simplified version of the above standard.

Hope this helps

Assuming that your gate valve is wide open, then you only have to estimate the vent noise.

Several of the valve companies (Fisher Rosemount, etc) have estimates to vent stack noise. Banerek also documents the noise estimate.
