Example 20-2 A spent nuclear fuel rod of length 1.4 m and diameter 4 cm is buried 4 m in the ground parallel to the surface. The rod generates 300 W of heat. Assume o1.2W/(m C)soilk=. If the surface of the soil is at 15°C, what is the surface temperature of the rod? Solution: Use the first configuration in Table 11-1. In this case, z = 4m
