A pure aluminum plate is part of a heat shield for a manufacturing process. The aluminum plate has a thickness of 3.60 mm. The aluminum plate is insulated (on one side only) with Board and Slab insulation (Cellular glass, density of 145 kg/m³) 6.00 cm thick; which in turn is covered with a layer of Particle board (high density) 1.00 cm thick (The composite wall goes: aluminum/cellular glass insulation/Particle board). The temperature on the exposed surface of the aluminum plate is measured to be 78.0°C, while the outside surface of the Particle board is exposed to convection, T∞ = 22.0°c, hoo 17.0 W/(m²-K). The plate = has dimensions of 11.50 m long by 3.50 m tall. .• Draw and label a sketch of this system. Include dimensions, known temperatures, etc. • • Draw and completely label the corresponding 1-D steady-state conduction resistor diagram. Determine the heat transfer rate through this composite plate. • Calculate the temperature at the Cellular Glass insulation/Particle board interface.
