Two rooms, each a cube 4.5 m per side, share a 13-cm-thick brick wall. Because of a number of 100-W lightbulbs in one room, the air is at 35 ∘C, while in the other room it is at 12 ∘C. How many of the 100-W bulbs are needed to maintain the temperature difference across the wall? Express your answer as an integer (in bulbs)

Heat transfer question.
A large wall made of 10-cm-thick solid brick (k = 0.8 W/m.K, p 2000 kg/m3, and p 800 J/kg.K) is originally at a uniform temperature of 30°C. The wall is adiabatic (well insulated) on one side as shown in the figure. The other surface is suddenly exposed to convection air flow at 10°C, resulting in a heat transfer coefficient h=40W/m2.K. Fluid (4.1) Determine the temperature of both surfaces Gr 0 and x 10 cm) after 5 hr...
