Webthe length of the rod is L, the position along the rod is given by x, where 0 x L: Since the rod is insulated, there is no transfer of heat from the rod except at its two ends. We may therefore assume that the temperature u depends only on x and on the time t. 0 x L ∆ x Figure 1 The variation of temperature in an insulated rod. Consider a ... WebSep 9, 2024 · Heat flows in the opposite direction to the temperature gradient. The ratio of the rate of heat flow per unit area to the negative of the temperature gradient is called the thermal conductivity of the material: (4.3.1) d Q d t = − K A d T d x. I am using the symbol K for thermal conductivity. Other symbols often seen are k or λ.
