(b) A horizontal electronic component, 5 mm wide and 10 mm long with a surface temperature of 35°C dissipating 0.1 W by free convection from one side into air where the temperature is 20°C and k = 0.026 W/m.K. (c) Air at 4°C (k = 0.024 W/m.K) adjacent to a wall 3 m high and 0.15 m thick made of brick with k = 0.3 W/m.K, the inside temperature of the wall is 18°C, the outside wall temperature is 12°C. Assume one dimensional conduction.
