AI Explanation
The correct answer is A) the bottom of the tubular bowl type. In a centrifugal lube oil purifier, the dirty oil inlet is located at the bottom of the tubular bowl type unit. This allows the heavier contaminants and sludge to settle to the bottom of the bowl, while the cleaned oil is discharged from the top of the unit. The other options are incorrect because: B) the location of the dirty oil inlet on a disk type purifier depends on whether it is being operated as a separator or a clarifier; C) the dirty oil inlet on a disk type purifier is only located at the bottom; and D) the dirty oil inlet on a tubular bowl type purifier is not located at the top.
