A pipe has inside diameter of 4 cm and wall thickness of 10 mm. At the inside surface of the pipe, the temperature is 70°C and at the outside surface, the temperature is 30°C. If the heat lost from the pipe per unit length is 6000 W/m, what is the thermal conductivity of the pipe material? Express your answer in W/m°C.
