Here we have a conical section made from a material with a thermal conductivity value of k=3.46 W/mK (assume that k is constant). The circular cross section diameter value is D= 0.25x. The small end is at x= 60 mm and the large end at x = 300 mm. The temperature values are T= 400 K and T= 600 K (the lateral surface is well insulated). a)Derive an equation that shows temperature distribution b)Calculate heat transfer rate qx. T = 600 K qx T = 400 K x = 0.05 m x = 0.25 m X4
