Definition (PT-BR)
Semi-formal axiom (Aristotelian)
Axiom type
LLM classification basis: structure-based → ⊑
This concept is primarily defined by its physical mechanism - the use of centrifugal force via rotating impellers to achieve pressure increase. All definitions emphasize the constructive aspect (impeller, centrifugal force, vanes) rather than a unique functional role beyond generic pumping.
