Inner surface of a cylindrical shell of length 1 and of material of thermal conductivity k is kept at constant temperature T and outer surface of the cylinder is kept at constant temperature T such that T T as shown in figure Heat flows from inner surface to outer surface radially outward Inner and outer radii of the shell are R and 2R respectively Due to lack of space this cylinder has to be R replaced by a smaller cylinder of length inner and outer radii and R respectively and thermal 4 conductivity of material nk If rate of radial outward heat flow remains same for same temperatures of inner and outer surface i e T and T then find the value of n T 7 0 0 4
