Problem 3: A flat panel used on a spacecraft is fabricated from a single layer of SIC/SIC composite, 0.035 m thick. The spacecraft has inner air temperature Tinside = 298 K and it is in orbit with the panel exposed only to deep space, where Tspace=0 K. This material has kcomposite 6.38 W/m-K and the average emissivity is = 0.79. The inner surface of the panel is exposed to airflow resulting in hinside 45 W/m²-K. 1. Determine the outer surface temperature T₂ 2. Determine the heat flux (q")
