Common questions
What is the Heat Conduction formula?
Heat Conduction is written P = kAΔT/L. Rate of heat flow through a material. It belongs to Thermodynamics, under Heat & Temperature.
What are the units in P = kAΔT/L?
In SI units, P is heat flow rate, measured in kg·m²/s³; k is thermal conductivity, measured in kg·m/(s³·K); A is cross-sectional area, measured in m²; ΔT is temperature difference, measured in K; L is length, measured in m.
How is the Heat Conduction formula derived?
Fourier's law of heat conduction. The result is P = kAΔT/L.
