Question C1: The schematic diagram of a metal bar, made of Cadmium, is shown in the figure below. Two identical cavities were created on each side of this metal bar and filled with Silicon. The left face of the metal bar is connected to a constant temperature heat source of 150C. The right face of the metal bar is connected to a fan so that heat can transfer from the right surface to the surrounding environment by convection. The temperature of the surrounding environment and convection heat transfer coefficient are -10C and 85 W/m K, respectively. The top and bottom surfaces of the bar are properly insulated. The width of the bar is 1.0 m. Assume a 1-D heat conduction and neglect the radiation heat transfer, (a) Draw the thermal circuit of this system and calculate different resistances. (b) Calculate the total heat transfer rate through this bar. (c) What is the temperature at the right face of the bar? 12 cm 8 cm 10 cm Cadmium 4 cm 4 cm 25 cm Silicon Silicon Fan To h
