A row of 3-ft-long and 1-in-diameter used uranium fuel rods that are still radioactive are buried in the ground parallel to each other with a center-to-center distance of 8 in at a depth of 15 ft from the ground surface at a location where the thermal conductivity of the soil is 0.6 Btu/h·ft·°F. If the surface temperature of the rods and the ground are 410°F and 60°F, respectively, determine the rate of heat transfer from the fuel rods to the atmosphere through the soil.
