Show that the heat flow rate through a spherical shell of inner and outer radii r1 and r2 respectively is given byHeat flow rate = 4πkr1r2 (T1 - T2)/ (r2 - r1)where k is the thermal conductivity of the shell, and the inner and outer surfaces are maintained at the temperatures T1 and T2 respectively. (Surface Area of asphere is given by 4πr2)
