A steel pipe with 5-cm OD is covered with a 6.4-mm asbestos insulation [k =0.096 Btu/h ft. °F] followed by a 2.5-cm layer of fiberglass insulation [k =0.028 Btu/h ft. °F]. The pipe-wall temperature is 315°C, and the outside insu- lation temperature is 38°C. Calculate the interface temperature between the asbestos and fiberglass. %3D W
