Question

A typical section of a building wall is shown. This section extends in and out of the page and is repeated in the vertical direction. The wall support members are made of steel (kB = 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 (kA = 0.03 W/m·K) and measures 8 cm (t23) × 60 cm (LA). The inner wall is made of gypsum board (k12 = 0.5 W/m·K) that is 1 cm thick (t12) and the outer wall is made of brick (k34 = 1.0 W/m·K) that is 10 cm thick (t34). What is the temperature on the interior brick surface (T3, °C), when T1 = 20°C and T4 = 35°C?

I am looking for T3, not heat flux. Thanks!
