Question 293Motor Plants - Assistant Engineer

The correct answer is B) the centrifuge disc stack. The illustration MO-0112 likely depicts a centrifuge used for oil-water separation, and the "N" symbol represents the centrifuge disc stack, which is a key component of the centrifuge. The disc stack is responsible for creating the centrifugal force that separates the oil and water phases within the centrifuge. The other answer choices are incorrect because they do not accurately describe the "N" symbol in the context of a centrifuge used for oil-water separation. Options A, C, and D do not directly correspond to the components or operation of a centrifuge as shown in the illustration.
