= = Q1. Consider a plane wall with a thickness of L 0.06 m and thermal conductivity k = 1.2 W/m K placed in space. The wall is adorned with white porcelain tiles, featuring an emissivity of 0.85 and a solar absorptivity of a = 0.26, as illustrated in figure given below. The inner surface of the wall is consistently maintained at a temperature T 300 K, while the outer surface is exposed to solar radiation at a rate of 800 W/m. The outer surface also loses heat through radiation to deep space at 0 K. Determine the temperature distribution across the wall and calculate the rate of heat transfer through the wall under steady operating conditions. Additionally, create plots depicting the temperature distribution when: (a) The thermal conductivity k varies between 0.5 and 2 W/mK. (b) The emissivity e varies between 0.8 and 0.9. (c) The absorptivity a varies between 0.2 and 0.3.
