A cylindrical 30 cm diameter flue liner is centered in a 40m high, 60 cm square chimney\n(k = 1.34W/m.k). The average temperature of the combustion products is 400 °C, and\nthe ambient temperature is 15°C.\na) Draw a schematic diagram for the problem [4 marks]\nb) Compute the conduction shape factor between the liner and the chimney\n[4 marks]\nc) Compute the conduction resistance between the liner and the chimney\n[5 marks]\nd) Compute the rate of heat loss from the chimney if the inside and outside heat\ntransfer coefficients are $h_i = 90 \text{ W/}m^2 \cdot k$ and $h_o = 10 \text{ W/}m^2 \cdot k$, respectively.
