AI Explanation
The correct answer is D) is self desludging. The key difference between the centrifuge bowl shown in the illustration and a traditional tubular bowl is that the illustrated unit has a conical shape, rather than straight, vertical interior surfaces. This conical shape allows the bowl to be self-desludging, meaning it can continuously remove accumulated solids (sludge) without needing to be shut down for manual cleaning. The other answer choices are incorrect because: A) the discharge ring is still required, B) the rotational speed is not specified, and C) there is no information provided about the rotational speed difference compared to the old tubular bowl.
