question
A tube of 3.0 in. outside diameter is covered with 2 in. thick layer of an insulating material whose thermal conductivity varies with temperature is given by k = 0.4 + 8 × 10^-4T where T is in °F. If the inside and outside surface temperatures of the insulating layer are 400°F and 150°F, determine the rate of heat loss per foot length of the tube.
