We have 30357 kg/h of Natural Gas in pipe at 6 kg/cm2g and flowing density 4.89 kg/cm3. Using 14" pipes, we find that actual gas velocity 64.86 ft/s and sonic velocity 23.02 ft/s (based on K=1.33).Excel spreedsheet calculation attached. Are my calculation correct? How much this condition affect to noise and vibration ? thanks for your advise.
