Webb31 aug. 2024 · Some describe pump cavitation as the creation and collapse of the air bubbles in a fluid. While they may appear to look like air, those bubbles are technically a cavity, gaseous vapor, or vacuum. While cavitation is possible in all pump types, it is more common in centrifugal pumps where the bubbles quickly develop around the impeller’s … WebbEnergy Cost Theory. The concept behind energy usage for a water distribution system is simple: pumps are used within a system to add energy, counteracting the energy losses that occur due to pipe friction and other losses. The cost of operating these pumps, however, can be one of the largest expenses that a utility incurs during normal operations.
