Laws of Heat Transfer

Fourier’s law of conduction Rate of heat transfer by conduction along a given direction is directly poportional to the area of the heat transfer lying perpendicular to the direction of heat transfer. In the above expression, -ve sign denotes that as x↑ T↓ “Heat always flows in direction of downhill of temperature.” k is thermal conductivity. …
