Q1/A steel pipe of outside diameter of (5.1 cm) is insulated with a (0.64 cm) thickness of asbestos followed by a (2.54 cm) layer of fiber glass. If the pipe wall is (315.6 °C) and the outside insulation is (37.8 °C), what is the temperature between the asbestos and fiber glass? The thermal conductivities for asbestos and fiber glass are (0.166 W/m. °C) and (0.0485 W/m. °C), respectively.
