🔍 Key Concepts

• Fourier’s law of heat conduction for a flat wall • Relationship between heat transfer rate (Q), area (A), temperature difference (ΔT), and wall thickness (L) • Whether a larger distance for heat to travel through a solid makes conduction easier or harder

💭 Think About

• If you double the temperature difference across the wall, what should happen to the rate of heat transfer, assuming all else stays the same? • If you make the wall thicker, does that usually make it easier or harder for heat to flow by conduction? How should that show up in the formula? • Think about a larger contact area between hot and cold regions: should that increase or decrease the total heat transfer rate?

✅ Before You Answer

• Make sure the correct relationship shows directly proportional to ΔT if more temperature difference means more heat flow. • Check whether increasing wall thickness should make the heat transfer rate larger or smaller. • Confirm that a larger heat transfer area should increase total heat transfer, not reduce it.

What statement is true concerning the heat transfer rates through a heat exchanger boundary wall by conduction?

Heat transfer rates are inversely proportional to the temperature gradient across the wall, and directly proportional to the area of the wall and the wall thickness.
