Question 244General Subjects - Assistant Engineer

The correct answer is D) prevent separated oil from mixing with the incoming bilge water. The function of item "7" in the illustration GS-0153 is to act as a weir or baffle that prevents the separated oil from re-mixing with the incoming bilge water. This helps maintain the oil/water separation within the device and ensures that the oil can be properly discharged or disposed of separately. The other answer choices are incorrect because: A) does not describe the function of item 7, B) refers to a different component, and C) does not fully capture the purpose of preventing re-mixing of the oil and water.
