2. Radioactive waste (K_w=22.5W/mK) is stored in a cylindrical steel (ks=15W/mK) container with inner and outer radii of ri=0.45m and r=0.5m, respectively (see figure). Thermal energy is generated uniformly within the waste material at a volumetric rate of Q=20000W/m3. The outer surface of container is exposed to water at TW=30C, with a convective heat transfer coefficient of h=150W/m2K. The ends of the cylindrical assembly are insulated so that energy loss through the top and bottom ends can be neglected. 1. Calculate the temperature difference between the hottest and coldest points in the waste material (in " C ) 2. Calculate the temperature difference between inner and outer surface of the stainless-steel container (in C ) 3. Calculate the outside surface temperature of the stainless steel (in C ) 4. Calculate the generation of heat per unit length of the container (in W)
