🔍 Key Concepts

• Jacket water cooling system on a diesel engine – what fluid is being cooled and what removes the heat • Difference between sensible heat (temperature change with no phase change) and latent heat of vaporization (heat involved in changing liquid to vapor or vapor to liquid) • In a typical heat exchanger between jacket water and sea water, which side is the primary purpose: cooling jacket water or heating sea water?

💭 Think About

• Look at where label "3" is located in the diagram: which lines connect to it, and which fluid (jacket water or sea water) passes through it? • Ask yourself whether the jacket water in a normal engine cooling circuit is supposed to boil/condense, or just change temperature while staying liquid. • For each answer choice, decide whether it describes a device whose main job is to cool the jacket water, or to cause a phase change, or to warm another fluid instead.

✅ Before You Answer

• Verify that jacket water remains liquid in normal operation (no boiling, no condensation) and therefore involves removal of sensible heat only. • Confirm that a cooler’s primary purpose in this system is to remove heat from the jacket water, not to raise the sea water temperature for its own sake. • Check whether latent heat of vaporization would apply here – does this system have any component where water is intentionally evaporated or condensed?

What is the function of the device labeled "3" shown in the illustration? Illustration MO-0111

The jacket water cooler is used to raise the temperature of the sea water flowing through it.

The heat exchanger serves to heat the jacket water during cold water operation.

The device specifically serves to remove the latent heat of vaporization from the jacket water.

The cooler removes sensible heat from the jacket water.
