As per my understanding pump vendors size centrifugal pumps (consider an API 610, OH2) for the rated flow(Rf). However, if the MCSF flow is through an orifice, this flow needs to be added to the rated flow, and the new flow (Initial rated flow + MCSF) becomes the rated flow (New rated flow...
Would like to hear your opinions on the below points regarding the surge in centrifugal fans/Blowers. (API 673/ API 560)
1. Is surge a major issue in low-power(<50 kW) centrifugal fans?
2. Is it bad or not preferred to operate on the left side of the surge line for such a blower?
3. What are...
