🔍 Key Concepts
• Relationship between the vertical position of fittings on a tank and their function (top = vents/alarms, mid = equalization/pressure, bottom = drains/fluidizing water)
• How internal dashed lines usually represent piping or lines running inside the tank from an external connection
• In a tank carrying pulverized material that is fluidized with water, what must be located near the bottom versus nearer the top/sides
đź’ Think About
• Look closely at where label E is located on both the side view and the top view: is it high, mid-level, or low on the tank, and is it connected to internal piping?
• Ask yourself which of the four choices would most logically be installed at that particular height and orientation on a pressurized tank of pulverized material.
• Compare E with the other labeled connections (like A, B, C, D, G, H): which ones clearly look like top‑mounted alarms/vents and which look like bottom‑mounted fluidizing inlets or drains?
âś… Before You Answer
• Verify whether E is drawn as a nozzle on the shell or top and whether any dashed internal pipe is aligned with it.
• Check if the function you choose for E would reasonably be placed at that exact vertical level in a tank intended to fluidize pulverized material.
• Make sure your choice for E is not duplicating a function that is already clearly represented by another labeled component (for example, if another letter obviously shows the bottom fluidizing water inlet).
