Definition
A method of separating substances of different densities by spinning them rapidly so that the heavier components are forced outward while the lighter components remain closer to the center of rotation.
Plain English
Spinning something fast so that heavier bits get flung to the outside and lighter bits stay near the middle, separating them.
Context Anchor
Seen in aircraft engine and maintenance discussions, especially where oil or fuel contamination is separated by spinning action.
Derivation
From Latin 'centrum' (center) and 'fugere' (to flee). Literally 'fleeing from the center' — which is exactly what the heavier material does when spun.
Why Pilots Care
Centrifuging is how some oil filters, fuel separators, and propeller governors do their job. Understanding the principle helps a pilot grasp why contaminants collect where they do and why certain components rely on engine RPM to function.
Analogy
Like spinning a wet salad spinner — the water flies outward through the holes while the lettuce stays in the middle.
Intuition Check
Centrifuging is not the same as filtering through a screen. It separates material by spinning it and using the difference in weight between the materials.
Example Sentence 1
The oil separator works by centrifuging the air-oil mixture so that the heavier oil droplets collect on the outer wall and drain back into the sump.
Example Sentence 2
Centrifuging the fuel removed any water before the preflight inspection.
