A common problem involves the radial heat flow through a material between two concentric cylinders, say through the insulation between an inner pipe and its outer jacket. Consider an inner cylinder of radius r1 at temperature T1 and an outer cylinder of radius r2 at temperature T2. Show that the radial rate of heat flow per unit length, L, is given by: (1/L) dQ/dt = 2p k(T1 – T2) / ln(r2 /r1). Assume the thermal conductivity of the material, k,...
