Heat Conduction Calculator
Calculate heat transfer rate through conduction using Fourier's law of heat conduction
About this calculator
The Heat Conduction Calculator determines the rate of heat transfer through solid materials using Fourier's law of heat conduction. This tool is essential for engineers, architects, and students working with thermal analysis, building insulation design, and heat exchanger calculations. By inputting material properties like thermal conductivity, cross-sectional area, temperature difference, and thickness, you can quickly calculate how much heat energy flows through a material per unit time, helping optimize thermal efficiency and energy conservation in various applications.
How to use
Enter the material's thermal conductivity (W/m·K), cross-sectional area (m²), temperature difference between surfaces (K or °C), and material thickness (m). The calculator applies Fourier's law equation Q = -kA(ΔT/Δx) to determine the heat transfer rate in watts, providing instant results for your thermal analysis needs.
Frequently asked questions
What is thermal conductivity and how do I find it?
Thermal conductivity measures a material's ability to conduct heat. Common values: copper (400 W/m·K), steel (50 W/m·K), glass (1 W/m·K), wood (0.1 W/m·K).
What units should I use for temperature difference?
Use either Celsius or Kelvin for temperature difference. Both give the same result since we're calculating the difference, not absolute temperature.
Can this calculator handle composite materials?
This calculator works for single homogeneous materials. For composite materials, calculate each layer separately or use equivalent thermal conductivity values.
