Consider two tubes of the same diameter (D₁ = 20 cm), length, and surface temperature (T₁). One tube is properly centered in a cylindrical insulation of D₂ = 40 cm; the other tube is placed in eccentric with the same diameter cylindrical insulation, where the distance between the center of the tube and the center of the insulation is z = 5 mm. If both configurations have the same outer surface temperature T₂, determine which configuration has the higher rate of heat transfer through the insulation.
