The diagram shows a conical section fabricated from pyroceram. It is of circular cross section with the diameter D=ax, where a=0.25. The small end is at x1=50mm and the large end at x2=250mm. The end temperatures are T1=400K and T2=600K, while the lateral surface is well insulated. pyroceram (500K):k=3.46W/mK. 1. Derive an expression for the temperature distribution T(x) in symbolic form, assuming one-dimensional conditions. Sketch the temperature distribution. 2. Calculate the heat rate qx through the cone
