To solve this problem, we can use the concept of thermal resistance:
q = -1.2 * 1 * 100 = -120 W/m²
A large plane wall of thickness 40 cm has a thermal conductivity of 1.2 W/m°C. One side of the wall is maintained at a temperature of 80°C, while the other side is maintained at 40°C. Determine the heat flux through the wall. To solve this problem, we can use the
The thermal resistances of the three layers are: To solve this problem
R = L / k * A
