SUMMARY
The discussion focuses on the mechanics of multi-stage centrifugal pumps, specifically how multiple impellers affect flow rate and head. It is established that while the flow rate remains consistent from impeller to impeller, the head increases with each additional impeller. Minor increases in flow capacity may occur at each stage to compensate for losses due to backward leakage across the hub and eye rings of the previous impeller, but these are negligible.
