In a boiler installation coal is burnt at the rate of 1.9 x 10³ kg/hr and hot gases are generated at the rate of 18 kg per kg of coal burnt. Hot gases are at the temperature of 600 K and ambient air temperature is 300 K Different pressure losses in furnace grate, flues, bends and chimney are measured to be 6 mm, 5 mm, 3 mm, and 1 mm of water respectively. Hot gases leaving chimney have velocity equivalent to 1.2 mm of water column. Considering the actual natural draught to be 80% of theoretical draught determine the height and diameter of chimney
