Question.2 (7 × 1=7marks)
Consider a plane wall made up of three different layers of materials having
different thermal conductivities and thicknesses of the layers as following:
k? = 19 W/m. K, k? = 10 W/m. K, k? = 3 W/m. K
x? = 10 cm, x? = 5 cm, x? = 15 cm
T? = 200 °C, T? = 50 °C,
Area = 2 m²
Compute the temperature profile(s) with full
equation(s)
