Question

Equation of fourier second law

Answer 1

Answer:

Fourier's law states that the negative gradient of temperature and the time rate of heat transfer is proportional to the area at right angles of that gradient through which the heat flows. Fourier's law is the other name of the law of heat conduction.

Fourier's law differential form is as follows:

Fourier's law differential form is as follows: q=-k\bigtriangledown T. Where, q is the local heat flux density in W.m. 2. k is the conductivity of the material in W.m-1

Answer 2

Answer:

“Fourier's law of thermal conduction states that the rate of heat transfer through a material is proportional to the negative gradient in the temperature and the area (perpendicular to the gradient) of the surface through which the heat flows.” Processes of heat transfer are measurable in the form of rate equations.

Fourier's law states that heat flux is proportional to thermal gradient: q = -k dT/dx, where k is thermal conductivity.
