Extracted text: Q3) Determine the heat transfer through the composite wall shown in the figure below .Take the conductives of A, B, C, D & E as 50, 10, 6.67, 20& 30 W/mK respectively and assume one dimensional heat transfer. Take of area of A=D= E =lm² and B=C=0.5 m² .Temperature entering at wall A is 800 °C and leaving at wall E is 100 °C. В A D E
