What is the Heat Transfer Calculator?

The Heat Transfer Calculator helps students and learners determine the rate of heat transfer through a material using Fourier’s law of heat conduction. By entering the thermal conductivity, cross-sectional area, temperature difference, and material thickness, the calculator quickly computes how much heat passes through the material per unit time. This allows users to study thermal processes, analyze insulation efficiency, and understand energy flow in solids.

How to Use:

1. Enter Thermal Conductivity (k): Type the material’s thermal conductivity in W/m·K.
2. Enter Cross-sectional Area (A): Input the area through which heat flows in m².
3. Enter Temperature Difference (ΔT): Input the temperature difference across the material in Kelvin.
4. Enter Thickness (d): Type the thickness of the material in meters.
5. Click “Calculate”: The calculator applies Fourier’s law to compute the heat transfer rate (Q).
6. Review Result: The output shows Q in watts (W), indicating how much heat is transferred per second.
