question

A 6 in. I.D. and 6.5 O.D. stainless steel (k = 26 Btu/hr-ft-°F) pipe is insulated with a 3.5 in. thick layer of an insulating material (k = 0.04 Btu/hr-ft °F). If the inner surface of the pipe is at 500°F and the outer surface of insulation is at 150°F, determine the rate of heat loss per foot length of the pipe and the temperature at the interface between the pipe and the insulation.
