If a heat exchanger is designed to heat heavy fuel oil using steam as a heating medium, what statement is true?

🔍 Key Concepts

• Sensible heat vs latent heat (what changes in each case) • What happens to steam when it condenses on a colder surface • What happens to the temperature and phase of heavy fuel oil during normal heating in a heat exchanger

💭 Think About

• When you heat heavy fuel oil in a heat exchanger, does its temperature change, its phase change, or both? Which type of heat is associated with that? • When steam is used as a heating medium and gives up energy to the fuel, is the steam typically condensing or just cooling as a gas? What type of heat transfer is associated with condensation? • Think about which fluid is changing state and which fluid is only changing temperature in this process.

✅ Before You Answer

• Verify which type of heat (sensible or latent) is linked to a change of temperature without phase change. • Verify which type of heat is linked to phase change at essentially constant temperature. • Identify which medium (steam or heavy fuel oil) is undergoing a phase change in this typical marine heat exchanger arrangement.

If a heat exchanger is designed to heat heavy fuel oil using steam as a heating medium, what statement is true?

The heavy fuel oil gains sensible heat, and the steam loses latent heat.

The heavy fuel oil loses sensible heat, and the steam gains latent heat.

The heavy fuel oil gains latent heat, and the steam loses sensible heat.

The heavy fuel oil gains sensible heat, and the steam loses sensible heat.
