A copper sheet of thickness 2.70 mm is bonded to a steel sheet of thickness 4.10 mm. The outside surface of the copper sheet is held at a temperature of 170.0 °C and the steel sheet at 27.0 °C. (The thermal conductivity is 386 W/(m K) for copper and 16.3 W/(m K) for steel.)
a) Determine the temperature of the copper–steel interface.°Cb) How much heat is conducted through 1 m2 of the combined sheets per second?W
