1. A fumace wall has an inner layer of silica brick with ki = 1.07 W/m-K, and an outer layer of masonry brick with k = 0.66 W/m-K. Fumace gas conditions are T; = 400 °C and T. = 25 °C. In addition, hi = 45 W/m²K and ho = 25 W/m K. It is desired that the heat loss be 800 W/m², and that the interface temperature, Tz, be 150 °C. Compute the thickness Li and L2 needed.
