The inner and outer surface area of a hollow sphere are 2 m2 and 8 m2 respectively. For a given temperature difference across the surface, the heat flow is to be calculated considering the material of sphere as plane wall of the same thickness. What is the equivalent mean area (m2) normal to the direction of flow?
