Frequently Asked Questions (FAQ)
What is the Conduction Heat Transfer Calculator (Fourier's Law) and how does it work?
Thermal engineering and HVAC design tool. Applies Fourier's Law to quantify heat energy loss or gain across solid barriers.
How do I use this Conduction Heat Transfer Calculator (Fourier's Law)?
Enter or Select Material Thermal Conductivity ($k$ in W/(m·K), e.g. Concrete = 1.4, Fiberglass = 0.04). Enter Surface Area ($A$ in m²). Enter Hot Side Temperature ($T_1$ in °C). Enter Cold Side Temperature ($T_2$ in °C). Enter Wall / Insulation Thickness ($L$ in meters). View Calculated Heat Transfer Rate in Watts (W) and BTU/h.
What mathematical formula is used in this calculation?
Fourier's Law: q = (k * A * (T1 - T2)) / L. 1 Watt = 3.41214 BTU/h.
