Question 1 of 27070

Fuel density is easily checked on board ship to facilitate proper fuel treatment. What is the maximum fuel density at 15°C allowed for proper centrifugation to take place?

🔍 Key Concepts

• Fuel oil density at 15°C and how it affects separation in a centrifuge • Difference in density between fuel oil and water needed for efficient separation • Typical density range of marine fuel oils designed for centrifugal purification

💭 Think About

• Think about how a centrifuge separates two liquids of different densities. What must be true about the density difference between fuel and water for the separation to work well? • Look at the answer choices: which values are more realistic for heavy fuel oil density at 15°C used with purifiers, and which are clearly too light or too heavy? • Consider that water has a density of about 1000 kg/m3 at around this temperature. How close can fuel density get to that value before separation becomes inefficient?

✅ Before You Answer

• Compare each choice to water density ~1000 kg/m3 and eliminate values that would leave too little density difference for good centrifugation. • Recall or look up the typical maximum density rating of marine fuel purifiers (often specified at 15°C) and see which option is in that ballpark. • Verify which values represent realistic marine fuel densities (not lubricating oils or impossible values) used with standard centrifugal separators.
