A stainless steel pipe [thermal conductivity = 17 W/(m.C)] is being used to convey heated oil. The inside surface temperature is 13 degrees C. The pipe is 2 cm thick with an inside diameter of 8 cm. The pipe is insulated with 0.04m thick insulation [thermal conductivity = 0.035 W/(m.C)]. The outer insulation temperature is 25 degrees C. Calculate the temperature of the interface between steel and insulation, assume steady-state conditions.
