Steady heat conduction through a flat layer
Estimate steady one-dimensional heat flow through a flat layer with known conductivity, area, thickness, and temperature difference.
Method and scope
Q̇ = kAΔT/L.
Use steady heat conduction through a flat layer for educational calculation or a clearly scoped arithmetic estimate. Intended for Learners, General educational use.
Inputs- Thermal conductivity — W/(m·K)
- Area normal to heat flow — m², ft²
- Temperature difference — ΔK, Δ°C, Δ°F
- Layer thickness — m, mm, cm, in
SOURCE AND LIMITS
Assumptions: Steady one-dimensional conduction through a homogeneous flat layer. Thermal conductivity is constant and edge effects are neglected.
Limitations: Real assemblies contain multiple layers, gaps, fasteners, and transient effects.
