Question 153General Subjects - 1st Asst/Chief

The correct answer is B) The oily-water mixture enters through valve "5" and exits the separator through valve "14" as processed liquid. This is the correct answer because in the normal processing mode, the oily-water mixture enters the separator through the input valve "5" and flows through the separation chamber, where the oil and water are separated. The processed liquid, with the oil removed, then exits the separator through the output valve "14". The other answer choices are incorrect because they do not accurately describe the normal direction of flow through the device while operating in the processing mode. For example, option A incorrectly states that the mixture enters through valve "4", and option C incorrectly states that the mixture enters through the pressure control valve "2".
