A composite wall is to be constructed for a furnace. There's a window and two stainless steel bolts in the particular area that we are interested in. The temperature outside the furnace (T2) is always 30C due to the hot processing environment. The dimensions and characteristics of the wall are displayed in the figure below: 502mm : 10mm I Aluminum T1 mm," T2 I] Glass I Stainless Steel 10mm I] Acrylic plastic 50mm 30mm 70mm 30mm Calculate heat flux through the wall at furnace temperatures, T1 = 400C and 800C. i) Use the thermal properties sheet provided. How will the heat flux change if we used copper bolts instead of stainless steel? Calculate the heat flux for both temperatures, T1 = 400C and 800C, using copper bolts. i) Do your calculations match your expectations?
