Now you are asked to consider the effects of radiation. The furnace sidewalls may beconsidered a blackbody and are kept at 1400 k. You may assume the titanium has an emissivity of 0.45. Provide a sketch of the control volume with various heat transfer contributions. Include the unsteady storage contributions. Write the control volumeenergy balance that includes both radiation and convection.
