Question:

A typical section of a building wall is shown in Fig. P17€“126. This section extends in and out of the page and is repeated in the vertical direction. The wall support members are made of steel (k = 50 W/m·K). The support members are 8 cm (t23) × 0.5 cm (LB). The remainder of the inner wall space is filled with insulation (k = 0.03 W/m·K) and measures 8 cm (t23) × 60 cm (LB). The inner wall is made of gypsum board (k = 0.5 W/m·K) that is 1 cm thick (t12) and the outer wall is made of brick (k = 1.0 W/m·K) that is 10 cm thick (t34). What is the temperature on the interior brick surface, 3, when T1= 20°C and T4= 35°C?
