The temperature difference between the wooden wall is 16⁰C, and the heat current per square metre of the wall is 7,325 W/m².
<h3>Temperature difference between the wooden wall</h3>The temperature difference between the wooden wall is calculated as follows;
- Let the brick wall = wall A
- Let the wooden wall = wall B
- Let the area of the walls = A
Q = KL(ΔT)
Q = 0.5 x 0.1 x (20 + 273)
Q = 14.65 W
<h3>Heat current per square meter of the Walls</h3>QA = W/A
QA = (14.65)/A
- Let the area of the wall = 10 cm x 2 cm = 0.1 m x 0.02 m = 0.002 m².
QA = 14.65/0.002
QA = 7,325 W/m²
