🔍 Key Concepts

• Identify what system the component labeled 23 belongs to in this diagram (jacket water vs. feedwater/steam system). • Recall how a shell-and-tube heat exchanger typically works: which fluid usually goes inside the tubes and which stays on the shell side. • Determine which fluid is acting as the heating medium and which is the heated medium in this waste‑heat boiler system.

💭 Think About

• Follow the piping to and from device 23: Do its inlets and outlets come from the engine jacket water circuit or from the feedwater pump/boiler drum? • Ask yourself: in this diagram, is the jacket water giving up heat or receiving heat? What does that imply about what happens to the feedwater as it approaches the steam drum (24)? • Compare answers C and D to what you know about typical marine boiler heat transfer processes. Do those terms realistically describe what happens in a diesel jacket-water heat exchanger?

✅ Before You Answer

• Verify which lines into 23 are labeled the same as the jacket water connections elsewhere in the drawing. • Confirm that the feedwater line from the pump passes through 23 before entering the steam drum (24). • Eliminate any options that mention heat-transfer phenomena (azeotropic, subliminal) that are not normally associated with a simple jacket‑water/feedwater heat exchanger.

What occurs within the tubes of the device labeled "23" shown in the illustration? Illustration MO- 0111

The feedwater flowing through the inside of the tubes is being heated by the jacket water on the outside of the tubes.

The heat from the jacket water passing within the tubes is being transferred to the feedwater on the outside of the tubes.

The heat of combustion from the engine is being transferred azeotropically, adding latent heat to the entering jacket water.

The heat being transferred is subliminal; therefore expansion is taking place within the tubes.
