In Exercise 63, what is the temperature at the interface of the cylinders?
In exercise A steel cylinder of radius 5.0 cm and length 4.0 cm is placed in end-to-end thermal contact with a copper cylinder of the same dimensions. If the free ends of the two cylinders are maintained at constant temperatures of 95oC (steel) and 15oC (copper), how much heat will flow through the cylinders in 20 min?
