Consider the 4-layered wall component shown below. + twa twe ty3 twa x Assume that the wall is subjected to a temperature of 20C on its left face and a temperature of 50C on its right face. The wall has an area A equal to 12 m?. Other material properties are specified in the table below for each layer. Layer Wall panel thickness t [mm] Conductivity [W/(mK)] 1 120 0.8 2 50 0.4 3 120 0.8 4 20 0.3 Determine following variables: (i) the temperature distribution through the wall thicknesses (ii) the density of heat flow rate (iii) the heat flow rate Note: If the question does not provide the values of the variables required to calculate the solution, make sure to select appropriate values for these variables based on your engineering judgment
