Heat Flux
What is the fundamental relationship for heat flux?
Expand Hint
The SI units for heat flux:
$$$Watts/meter^2=kg/s^3$$$
Heat flux is the energy flow per unit of area per unit of time. It is also a vector (direction and magnitude), and is typically expressed by Fourier's law (simplified in one dimension):
$$$q_{x}=-k\frac{dT}{dx}$$$
where k = thermal conductivity, and dT is the temperature gradient.
