The thermal resistances of the three layers are:
dT/dx = (80 - 40) / 0.4 = 100°C/m
R_total = R1 + R2 + R3 = 0.5625 m²°C/W
q = -1.2 * 1 * 100 = -120 W/m²
where q is the heat flux, k is the thermal conductivity, A is the area, and dT/dx is the temperature gradient.
where R is the thermal resistance, L is the thickness of the material, k is the thermal conductivity, and A is the area.
