🔍 Key Concepts

• Sensible heat vs. latent heat – what changes during each type of heat transfer • In a lubricating oil cooler, which fluid is normally hotter when entering the heat exchanger? • Direction of heat flow – from higher temperature substance to lower temperature substance

💭 Think About

• Identify which fluid (lube oil or seawater) is being cooled and which is doing the cooling in this system. • Decide whether the oil and water are changing temperature, changing phase, or both. • Match the ideas of ‘gains heat’ and ‘loses heat’ with the normal direction of heat transfer in this type of cooler.

✅ Before You Answer

• Confirm that sensible heat involves a temperature change without a phase change. • Confirm whether either the lubricating oil or the seawater is expected to change phase in a normal marine lube oil cooler. • Make sure the fluid that starts hotter must be the one that loses heat, and the cooler fluid must be the one that gains heat.

If a heat exchanger is designed to cool lubricating oil using sea water as a cooling medium, what statement is true?

The lubricating oil loses sensible heat, and the sea water loses sensible heat.

The lubricating oil loses sensible heat, and the sea water gains sensible heat.

The lubricating oil loses latent heat, and the sea water gains latent heat.
