Find the rate of heat flow in the radial direction through a spherical shell of inner radius ri and outer radius ro for the case where the thermal conductivity varies as a linear function of temperature, k = k0(1 + βT) The inside shell is at temperature Ti and the outside at temperature To. Compare this with a case where the thermal conductivity is treated as a constant evaluated at the average temperature.
