🔍 Key Concepts

• Relative densities of oil, water, and solid particles (sediment) • How heavier vs lighter substances behave when allowed to settle undisturbed • Typical behavior of lube oil contamination in machinery spaces

💭 Think About

• Which of the three (oil, water, sediment) is densest and which is least dense? Arrange them from heaviest to lightest first. • If something is heavier than the surrounding fluid, where will it end up after settling for a long time? What about something lighter? • Think about what engineers usually drain off first from a settling tank or purifier—what does that tell you about layer order?

✅ Before You Answer

• Be clear on which contaminant (water or sediment) is heavier than oil and by how much in practical terms. • Confirm which substance is a liquid contaminant versus a solid contaminant; this helps imagine their behavior when settling. • Visualize a cross‑section of the tank and label bottom, middle, and top based on density order before matching to the choices.
