Question 1 of 27070

The normal characteristics and properties of lube oil will begin to break down if contaminated with water and __________.

🔍 Key Concepts

• Lube oil and water contamination in machinery spaces • Effect of heat and mixing on oil/water emulsions • Purpose of centrifuging lube oil on ships

💭 Think About

• Think about what operating condition will most quickly form an emulsion of oil and water, changing the oil’s normal properties. • Ask yourself which option is normally used on board to remove water from lube oil rather than make the problem worse. • Consider how temperature and motion affect the breakdown of oil when water is present.

✅ Before You Answer

• Identify which choice describes a process that is normally used to clean or purify lube oil rather than damage it. • Eliminate any option that would separate water from oil instead of mixing it more thoroughly. • Focus on which condition would most likely speed up chemical and physical breakdown of oil contaminated with water.
