Heat Conduction

Theory & Logic

Theoretical Background

Physics describes the fundamental mechanism of the universe. The Heat Conduction (Fourier Law) is an essential tool for understanding Heat Conduction (Fourier Law) in quantitative terms. Calculate Rate q = -kA(ΔT/Δx).

Mathematical Formulation

The relationship between the variables is governed by the following equation:

Result = (k × a × dt) ÷ dx
Eq 1.1: Governing Formula

Variable Legend

Symbol Parameter Unit
k Thermal Cond W/mK
a Area m²
dt Temp Diff K
dx Thickness m

Practical Calculation Example

Problem

Calculating the result when:

  • Thermal Cond = 15 W/mK
  • Area = 85 m²
  • Temp Diff = 55 K
  • Thickness = 95 m

Solution

Substituting into Eq 1.1:

Result = (15 × 85 × 55) ÷ 95
