🔍 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.
