🔍 Key Concepts

• Location and purpose of drain connections on heat exchangers or condensers • Difference between vent connections (usually at high points) and drain connections (usually at low points) • How high-pressure vs low-pressure sides are typically arranged in a condenser/heat exchanger shell

💭 Think About

• Look at where label "D" is placed vertically on the shell. Is it at a high point or a low point, and what kind of connection is usually found there? • Compare the size and position of the nozzle at "D" with other labeled connections used for steam supply or vents. What does that suggest about its function? • Think about what must be removed from the lowest parts of the shell during normal operation or shutdown. Which of the choices would match that need?

✅ Before You Answer

• Verify whether the connection at D is at the lowest point of that part of the shell or near it • Check whether any arrows or flow directions near "D" suggest removal of liquid rather than addition of steam • Confirm that vents are usually at high points to remove non‑condensable gases, while drains are at low points to remove liquids
