🔍 Key Concepts

• Look at how the water level is shown inside the steam drum and imagine what happens when the ship pitches fore and aft. • Identify which labeled parts are solid plates or baffles oriented across the drum that would slow or block water from rushing from one end to the other. • Distinguish between parts that handle steam flow (dry pipes, separators) and parts that mainly affect water movement inside the drum.

💭 Think About

• As the bow goes up and down, which internal structure would physically interrupt or break up the fore-and-aft sloshing of the water surface? • Which of the letters corresponds to something fixed, broad, and placed vertically or transversely in the path of water, rather than a narrow pipe or nozzle? • Compare C, L, M, and N: which one is most clearly designed to act like a partition or weir rather than a tube or header?

✅ Before You Answer

• Verify which item is drawn as a flat or plate-like structure extending down from the top region toward the water surface. • Check that the item you pick is located where it would be effective across much of the drum’s width, not just in one corner or low in the water space. • Confirm that the item you select is not primarily a steam outlet/dry pipe or a feed/distribution pipe, but instead a structure that modifies water motion.
