Question 1 of 27070

🔍 Key Concepts

• Fuel oil centrifugation principles (how a purifier separates oil and water/solids) • Role of the gravity disk in a purifier and what property it is matched to • Difference between fuel quality properties (like ignition, heating value) and physical separation properties (like density, viscosity)

💭 Think About

• Which fuel property directly affects how strongly it is pulled outward in a centrifugal field compared with water? • The gravity disk must be chosen so the oil–water separation line is in the correct place. Which test result tells you how heavy the oil is relative to water? • Are properties like ignition quality or calorific value important for combustion settings, or for mechanical separation in a centrifuge?

✅ Before You Answer

• Identify which test gives a numerical value used in purifier maker’s gravity disk selection charts • Distinguish between combustion-related properties and separation-related properties • Confirm which property determines the buoyancy and layering of oil vs. water in a centrifuge
