Question 60General Subjects - QMED

The correct answer is D) displace an equal amount of water from the bowl seal. When water is removed from lube oil passing through a centrifugal purifier, the water removed will displace an equal amount of water from the bowl seal. This is because the centrifugal force within the purifier bowl causes the water to separate from the oil, and the water is then expelled through the heavy phase discharge port. This displacement of water from the bowl seal is necessary to maintain the proper oil-water interface within the purifier. The other answer choices are incorrect because: A) the diameter of the oil column would not be narrowed, B) the water would not be retained in the bowl, and C) the amount of water displaced from the heavy phase discharge port would be equal to the amount removed from the oil, not less.
