Aflat panel used on a spacecraft is fabricated from a single layer of sic/sic composite, 0.020 m thick. the spacecraft has inner air temperature ti=310 k and it is in orbit with the panel exposed only to deep space, where to = 0 k. this material has kc=5.0 w/m2.k and ε=0.8. the inner surface of the panel is exposed to airflow resulting in hi = 70 w/m2.k. determine the outer surface temperature t2. determine q/a
