As shown in the Figure, a
composite material consists of a 0.9 cm layer of glass (pyrex) (A)
and a 0.4 cm layer of Teflon (B). The material separates two
gasses; one inside at Ti = 270°C with convective coefficient hi =
60 W/(m2 K) and one outside with convective coefficient ho = 28
W/(m2 K). It is know that the temperature of the exposed side of
the Teflon is Ts,o = 40°C. The two layers are not in perfect...
