For reciprocating compressor harmonic, acoustic and mechanical vibration analysis - Is there any guideline in API 618 which defines the physical extent up to which , from the source of pulsation the , frequency is to be maintained ?
Is there any guideline , whether we have to maintain a certain high frequency , up to what distance from source of pulsation ?
Say up to 100 diameters run or 200 diameters run ?

Is there any guideline apart from API 618 , say industry practice which defines that after how much distance the vibrations will die down ?
