Theory of radial flow of heat
WebbIn this Lecture, I have discussed1. Radial flow of Heat2. Spherical Shell Method 3. Cylindrical Flow of Heat WebbFourier’s law of thermal conduction (also known as the law of heat conduction) states that the rate at which heat is transferred through a material is proportional to the negative of the temperature gradient and is also proportional to the area through which the heat flows.
