The rear window of an automobile is defogged by passing warm air over its inner surface.
(a) If the warm air is at T8,i = 40°C and the corresponding convection coefficient is hi = 30 W/m2 · K, what are the inner and outer surface temperatures of 4-mm-thick window glass, if the outside ambient air temperature is T8,0 = - 10°C and the associated convection coefficient is ho = 65 W/m 2 . K?
(b) In practice T8,0 and ho vary according to weather conditions and car speed. For values of ho = 2, 65, and 100 W/m2.· K, compute and plot the inner and outer surface temperatures as a function of T8,0 for – 30 = T8,0 = O°C.
