Tag: Fick’s law

Engineering Essay In a previous post, I discussed heat transfer and derived Fourier’s law of heat conduction. In one dimension, it is given by: $$ q = -\kappa \frac{dT}{dx} $$ where \( q \) is the heat flux, \( \kappa \) is the thermal conductivity, and \( \frac{dT}{dx} \) is the temperature gradient. It can…
