Physics

A wall in a building has a width of 15 m and a height of 3 m. Itis made of several layers — a layer of motionless air with an Rvalue of 0.12 K m^2 / W, a 12.4 mm thick layer ofgypsum board with a thermal conductivity of 0.17 W/m K, a layer ofbrick with an R value of 1.7 m^2/ W, and another layer ofmotionless air with an R value of 0.12 K m^2 / W.

(a) If the temperature inside the building is 27.2°C and the temperature outside is 33.1°C, how much power will flow through the wall insteady state?

(b) How much power will flow if we add a layer of foaminsulation with an R value of 27.0 K m2/ W?
