Calculadora de Condução de Calor

The Heat Conduction Calculator calculates the rate of heat transfer by conduction through a material according to Fourier's Law. The formula used is Q/t = k * A * ΔT / d, where Q/t is the heat transfer rate (in watts), k is the thermal conductivity of the material, A is the cross-sectional area, ΔT is the temperature difference across the faces, and d is the thickness of the material.

This calculator is useful in engineering, architecture, and physics for sizing thermal insulation, estimating heat losses through walls or windows, and designing heating or cooling systems. For example, when calculating heat loss through a brick wall, you can determine the insulation thickness needed to maintain the desired indoor temperature.

To use the calculator, enter the values for thermal conductivity (k), area (A), temperature difference (ΔT), and thickness (d) in appropriate units. The result will be the heat conduction rate. It is important to use consistent units (e.g., k in W/(m·K), A in m², ΔT in K or °C, d in m).

Cautions: Fourier's Law assumes one-dimensional conduction in steady state with no internal heat sources. In real situations, convection and radiation may occur and are not considered. Also, thermal conductivity can vary with temperature; for greater accuracy, use average values over the temperature range of interest.
