When water is removed from lube oil passing through a centrifugal purifier, the water removed will __________.

Correct Answer: Option D — displace an equal amount of water from the bowl seal

Centrifugal purifiers maintain a water seal to prevent oil from escaping through the water discharge port. When water is separated from the oil, it accumulates in the bowl. To maintain the seal balance, the volume of water removed from the oil must displace an equal volume of water through the seal.
