Q

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

🔍 Key Concepts

• How a centrifuge separates substances based on density differences • Relative densities of lube oil, fuel oils, gasoline, and water • Which substance in lube oil is most critical to remove to protect bearings and machinery

💭 Think About

• Think about which contaminant is heaviest or lightest compared to lube oil and therefore separates well in a spinning bowl • Consider which contaminant is most harmful to lubricating properties and commonly targeted by purification systems • Ask yourself which substance is least likely to stay mixed with lube oil when subjected to high centrifugal force

✅ Before You Answer

• Compare specific gravity (density) of each option to that of typical lube oil • Recall what type of purifier/separator is normally installed in an engine room for lube oil treatment • Verify which contaminant is routinely checked for in lube oil analysis reports and is expected to be removed by the centrifuge
