The wall of an industrial kiln is built in refractory brick with 0.18 m thick, whose thermal conductivity is 1.7 W / (m.K). In steady state, the oven has a temperature of 1400 K on the inner wall and 1000 K on the outer wall. What rate of heat loss through the wall that is 1.6 m² in area? Draw a wall with a graph of temperature variation in its thickness.
