Prоblem 2. Heаt thrоugh the wаll оf аn autoclave Metal medical instruments, glassware and media for microbial culture are usually sterilized in autoclaves. These equipment have rigid and insulated sterilization chambers where the materials are exposed to high temperatures and pressures. The wall of the sterilization chamber in an autoclave is constructed of two 2-cm-thick steel plates (k = 15 W/m·K) 10 cm apart, with the space between them filled with fiberglass insulation (k = 0.035 W/m·K). The autoclave is in a room with circulating air at 30°C and the heat transfer coefficient of the moving air is 20 W/m2 ·K. This is illustrated in the figure below. If the temperature at the inner surface of the wall is 121°C, Determine: The heat flux through the wall, in W/m2 The temperature at the boundary of the insulation and the outer steel plate, in °C
