Determine the height of chimney above grate level. Where diameter of chimney is 1.75m and produces a draught of 1.8cms of water. Temperature of flue gases is 290oC. The flue gases formed per kg of fuel burnt are 23kg. Neglect the losses and assume atmospheric temperature as 20oC?

Determine the height of chimney above grate level. Where diameter of chimney is 1.75m and produces a draught of 1.8cms of water. Temperature of flue gases is 290oC. The flue gases formed per kg of fuel burnt are 23kg. Neglect the losses and assume atmospheric temperature as 20oC? Correct Answer H = 32.77m

GiveD = 1.75m, Draught in mm of water = 1.8cm = 18mm Flue gas temperature = Tg = 290oC = 563K Ambient temperature = Ta = 20oC = 293k Flue gases formed per kg of fuel burnt: (ma + 1) = 23kg
