The inner surface of a plane brick wall is at 60°C and the outer surface is at 35.8°C. Calculate the rate of heat transfer per m² of surface area of the wall, which is 220 mm thick. The thermal conductivity of the brick is 0.51 W/m·°C.

Step 1
Given: Inner surface temperature (Ti) = 60°C Outer surface temperature (To) = 35.8°C Temperature difference (ΔT) = Ti - To ΔT = 60°C - 35.8°C ΔT = 24.2°C Show more…

A plane wall 6.0 cm thick generates heat internally at the rate of 0.3 MW/m³. One side of the wall is insulated, and the other side is exposed to an environment at 93ºC. The convection heat-transfer coefficient between the wall and the environment is 570 W/m² · ºC. The thermal conductivity of the wall is 21 W/m · ºC. Calculate the maximum temperature in the wall.

The inner and outer surfaces of a $5-m \times 6-m$ brick wall of thickness $30 \mathrm{cm}$ and thermal conductivity $0.69 \mathrm{W} / \mathrm{m} \cdot^{\circ} \mathrm{C}$ are maintained at temperatures of $20^{\circ} \mathrm{C}$ and $5^{\circ} \mathrm{C},$ respectively. Determine the rate of heat transfer through the wall, in $\mathrm{W}$
