Hello everyone.
I have the natural frequencies of the piping system of a reciprocating pumping unit, I need to verify the separation margin indicated in Annex C of the API 674 standard.
If I have a triplex pump that rotates at 300 rpm, the significant frequency would be f=3*300/60=15 (Hz) as indicated by the standard, but I don't understand how to add inertial loads and how are determined.
I hope you can help me, thank you very much in advance.
