Determine the average value of coefficient of thermal conductivity

OBJECTIVES To investigate Fourier’s Law of linear conduction. RELEVANT THEORY AND WITH RELEVANT EQUATIONS    Heat transfer has direction as well as magnitude. The rate of heat conduction in a specified direction is proportional to the temperature gradient, which is the change in temperature per unit length in that direction. Heat conduction in a medium, …
