Heat Flow Rate vs Thermal Conductivity (k)
Formel
## Thermal Conductivity (Fourier's Law) Fourier's law describes the rate of heat conduction through a material. ### Formula **Q/t = k * A * DeltaT / d** where k is thermal conductivity, A is area, DeltaT is temperature difference, and d is thickness. Lower k means better insulation.
Lösungsbeispiel
Heat loss through a 10 m² wall, 10 cm fiberglass insulation (k=0.04), 20°C temperature difference.
- 01Q/t = k * A * DeltaT / d
- 02Q/t = 0.04 * 10 * 20 / 0.1
- 03Q/t = 8 / 0.1
- 04Q/t = 80 W
