Area of Composite Wall of 2 Layers evaluator uses Area of 2 Layer Wall = Heat Flow Rate 2 Layer/(Inner Surface Temperature 2 layer wall-Outer Surface Temperature of 2 Layer)*(Length 1/Thermal Conductivity 1+Length 2/Thermal Conductivity 2) to evaluate the Area of 2 Layer Wall, The Area of composite wall of 2 layers formula is defined as the area of the composite wall perpendicular to the heat flow required to maintain given temperature difference at given heat flow rate, length/thickness of the layers, and thermal conductivities. Area of 2 Layer Wall is denoted by Aw2 symbol.
