2) (30pts) Composite House Wall Let us calculate the conductive resistances (neglect convection outside and inside) in a composite house wall that is constructed of several materials (from outside to inside

with L= thickness) - Brick (L), Styrofoam (0.5L), Air Space (L), and Wood Paneling (0.1L). a) Make an accurate sketch of the problem and label all components. b) Show the form and calculate each resistance term separately. c) Combine resistance terms to calculate the overall heat flux (q/A). d) Calculate and accurately sketch the temperature profile through the composite wall Brick: k=0.66 W/m-K, Styrofoam: k = 0.033 W/m-K, Air: k = 0.025 W/m-K Wood Panel: k = 0.21 W/m-K
