Question 233General Subjects - Assistant Engineer

The correct answer is C) Ideally the flow of the oily-water should be low in flow rate and low in turbulence. This is correct because low flow rate and low turbulence facilitate the separation of oil from the oily-water mixture in an oily-water separator. Low flow rate allows more time for the oil droplets to coalesce and rise to the surface, while low turbulence minimizes emulsification of the oil, allowing it to separate more effectively. The other options are incorrect because high flow rate and high turbulence would disrupt the separation process and prevent the oil from effectively separating from the water.
