Thermal Resistance of Composite Wall with 3 Layers in Series evaluator uses Thermal Resistance of 3 Layer = Length 1/(Thermal Conductivity 1*Area of 3 Layer Wall)+Length 2/(Thermal Conductivity 2*Area of 3 Layer Wall)+Length 3/(Thermal Conductivity 3*Area of 3 Layer Wall) to evaluate the Thermal Resistance of 3 Layer, The Thermal Resistance of Composite Wall with 3 Layers in Series formula is defined as the total thermal resistance of a 3-layered composite wall, with the walls placed in series. Thermal Resistance of 3 Layer is denoted by Rth3 symbol.
