Question 270Motor Plants - Assistant Engineer
70% to passFor optimum results, centrifugal purification of heavy fuel oil should be accomplished with the fuel at the lowest practicable_______________.
Athroughput
Badditive percent
Ccetane number
DTBN number
AI Explanation
The correct answer is A) throughput. For optimum results in centrifugal purification of heavy fuel oil, the fuel should be processed at the lowest practicable throughput. This allows for more effective separation of contaminants and water from the fuel, as a lower throughput provides more residence time in the centrifuge and enhances the purification process. The other answer choices are incorrect because they do not directly relate to the optimal conditions for centrifugal purification. The additive percent, cetane number, and total base number (TBN) are not the primary factors that influence the effectiveness of the centrifugal purification process.
