Question 1 of 27070

A centrifuge will satisfactorily remove which of the listed substances from lube oil?

🔍 Key Concepts

• Centrifugal separation – how a purifier or clarifier separates substances by difference in density • What forms of contamination are typical in lube oil (solids vs. liquids) • Which contaminants are solids or form a separate phase, versus liquids that stay mixed with lube oil

💭 Think About

• Think about how a centrifuge actually works: does it throw out heavier solids, lighter liquids, or both? How does that compare to a filter? • Look at each option and ask: is this something that would exist as tiny solid particles or as a miscible liquid blended into the lube oil? • Which listed substance would most likely be removed by gravity/centrifugal settling, instead of needing a chemical or distillation process?

✅ Before You Answer

• Identify which option is clearly a solid contaminant, not a liquid fuel. • Decide which of the listed fuels would tend to be fully miscible with lube oil and therefore not easily separated by simple centrifuging. • Recall that lube oil centrifuges are primarily designed to remove water and solids (like sludge) from the oil; compare that to each choice.
