Example DT Wall of the house has 3 layers and aroa 20 x 3 m Thickness of layers are : L1=10mmm, L2=290mm, L=20mm Thermal conductivity of layers are: 2, = 0.9 W.mk , 22 = 0.75 W.m.K. is = 1.2 W.m .K. Temperature inside of the house is 20°C, convection heat transfer coefficient is ain = 7 W.m?K". Outside temperature is -15°C, convection heat transfer coefficient is cour = 17 W.m 2.K-1 Calculate : 1. Overall Heat-transfer coefficient (k=?) 2. Specific heat flux through wall (q = ?) 3. Total heat flux of wall (Q = ?) Surface temperature of wall (tin = ?, tox = ?)
