Industrial-process control valves - Part 8: Noise considerations - Section 4: Prediction of noise generated by hydrodynamic flow
Permits designers and operators of industrial-process plants to determine the noise generated by hydrodynamic flow through control valves. The sound power emitted into the pipe as well as the airborne noise emitted by the valve and piping system can be predicted.
