🔍 Key Concepts

• Piping layout in a dry bulk or liquid cargo tank – where would you normally put a suction line vs. a fill line vs. a vent? • Function vs. location – a vent must reach the vapor space, a suction line must reach near the lowest point, and a fill line usually terminates above the normal cargo level to avoid erosion/splashing. • Fresh‑water fluidizing sprinklers – for powdered cargo they are usually arranged low in the tank where they can break up or move the material.

💭 Think About

• On the side view, trace where line B starts outside the tank and where it ends inside. Does it go to the very bottom, stay high in the vapor space, or stop somewhere above the bottom? • Compare B with line D: which one reaches closer to the bottom (for suction) and which one looks better suited for loading from above? • On the plan (top) view, notice the diameter and position of the small fittings (like C, E, F) versus the larger pipes (B and D). Which fitting size and location is most typical for a vent?

✅ Before You Answer

• Verify which line in the drawing actually reaches nearest the bottom of the tank – that is the best candidate for a suction line. • Check which connection is small and located at the highest point of the tank – that is your best candidate for a vent. • Confirm that any sprinkler or fluidizing system would have outlets distributed low in the tank, not as one large single pipe from the top.
