Task 1 Calculate the heat transfer rate for the following composite wall configurations: (A) Consider a composite plane wall that includes a 10 mm-thick hardwood siding, 50-mm by 120- mm hardwood studs on 0.7m centres with glass fiber insulation (paper faced, 28 kg/m³), and a 15 mm layer of gypsum wall board. What is the thermal resistance per unit area associated with this wall (having 10 studs, each 2.5 m high). In addition, given the temperature at the inlet and outlet surface is 20 °C and -15 °C, calculate the heat transfer rate though this wall. stud insulation 50mm wood siding 120mm wall board
