Determine height and
(A)/(F)ratio to produce static draught of 18 mm of water column if mean flue gas temperature is 300 C , the atmospheric air temperature is 25 C . The gas constant for air is
287K(J)/(K)gK. and for flue gas
250K(J)/(K)gK. Atmospheric pressure is 101.325 kPa . Also define equivalent evaporation.
