Question:
Use the alternative conduction analysis of Section 3.2 to derive an expression relating the radial heat rate, \(q_{r}\), to the wall temperatures \(T_{s, 1}\) and \(T_{s, 2}\), for the hollow cylinder of Figure 3.7. Use your expression to calculate the heat transfer rate associated with a \(L=2 \mathrm{~m}\) long cylinder of inner and outer radii of \(r_{1}=50 \mathrm{~mm}\) and \(r_{2}=75 \mathrm{~mm}\), respectively. The thermal conductivity of the cylindrical wall is \(k=2.5 \mathrm{~W} / \mathrm{m} \cdot \mathrm{K}\), and the inner and outer surface temperatures are \(T_{s, 1}=100^{\circ} \mathrm{C}\) and \(T_{s, 2}=67^{\circ} \mathrm{C}\), respectively.
