Consider a 1.5-m-high and 0.6-m-wide plate whose thickness is 0.15 m. One side of the plate is maintained at a constant temperature of 500 K while the other side is maintained at 350 K. The thermal conductivity of the plate can be assumed to vary linearly in that temperature range as: k(T) = kl1 + BT) where ko = 25 W/m · Kand B transfer, determine the rate of heat conduction through the plate. Answer: 30,800 W 8.7 x 10 * K. Disregarding the edge effects and assuming steady one dimensional heat !!
