While operating the fuel oil centrifuge shown in the illustration, the fuel oil is being continuously ejected with the sludge and the seal water. The probable cause is the_______________. Illustration MO-0012
AI Explanation
The correct answer is B) the gravity disk inside diameter is too large.
When the fuel oil is being continuously ejected with the sludge and the seal water, it indicates that the separation process is not efficient. This can be caused by the gravity disk inside diameter being too large, which results in insufficient centrifugal force to properly separate the fuel oil from the sludge and water.
The other options are incorrect because: A) a smaller gravity disk diameter would increase the centrifugal force, improving separation; C) low back pressure would not cause the continuous ejection of fuel oil; and D) the number of disks in the stack is not the issue, as the problem is with the disk diameter itself.
