the table. The ? in the table indicates insulated boundary and Q is the distributed heat source. In
all cases assume the upper and lower boundaries are insulated. Assume that the units of length,
energy, and temperature for the values shown are consistent with a unit value for the coefficient
of thermal conductivity.

The bricks have the same cost and are laid in any manner, but we wish to design the most economical wall for a furnace with a temperature of 1040°C on the hot side and 200°C on the cold side. If the maximum amount of heat transfer permissible is 950 , determine the most economical arrangement using the available bricks.
