A flue passing hot exhaust gases has a square cross section, 300mm to a side. The walls are constructed of refractory brick 150mm thick with a thermal conductivity of 0.85 W/m*K. Calculate the heat loss from the flue per unit length when the interior and exterior surfaces are maintained at 350 and 25 C, respectively. Use a grid spacing of 75 mm.
