question

A 12 ft. long 4 in. diameter steel tube is insulated with 1 in. thick layer of an insulating material whose thermal conductivity is 0.05 Btu/hr-ft-°F. If the inner and outer surface temperatures of the insulating layer are 500°F and 100°F respectively, determine the radial rate of heat loss over the total length of the rod.
