Question: 1 problem solution must include a clear labeled schematic diagram...

Question details

1) problem solution MUST include a clear, labeled schematic diagram.

2) All assumptions must be clearly stated.

4) Calculations and UNITS must be included

17.28 Radioactive waste is stored in a cylindrical stainless- steel container with inner and outer diameters of 1 m and 1.2 m respectively, so that Ro -0.5 m and Ri -0.6 m. Thermal energy is generated uniformly within the waste material at a volumetric rate of 2 x 105 W/m3. The outer container surface is exposed to water at 25°C (Too-25°C), and the outer surface convective heat-transfer coefficient is h 1000 W/m2 . K. The ends of the cvlinder are insulated so that heat transfer is onlv in the r-direction. You may assume that over the temperature range of interest the thermal conductivity of stainless steel, ksteel, is 15 W/m - K and the thermal conductivity of the radioactive waste, krw, is 20 W/m- K What are the temperatures of the outer surface, To, and inner surface, T, of the stainless-steel container? What the maximum temperature within the radioactive waste? Where will this maximum temperature be located? Radioactive Waste Storage in a Stainless Steel Cylinder Additional Question. What is the mass flowrate (per unit length) of cooling water needed to remove the heat generated by the radioactive waste? Cooling water available at 5 C. and cannot go above 25 Q.

2) Every problem solution MUST include a clear, labeled schematic diagram. 3) All assumptions must be clearly stated. 4) Calculations and UNITS must be included at all times.
