Q) A chimney of 32 m height has produced a draught of 1.6 cm of water when hot gas temperature is 300°C and ambient temperature is 27°C. The coal used contains 81% carbon, 5% moisture and remaining is ash. Neglecting losses, find the % excess air supplied. Assume complete combustion of carbon in the fuel.

HMW-3 Combustion in a diesel engine is assumed to begin at TDC and proceed at constant pressure. The air/fuel ratio is 27/1, the calorific value of fuel is 43 MJ/kg, and the specific heat of combustion products is given by: Cy = 0.71 + 20x10-5 T where T is the combustion products temperature in K unit. The gas constant for these products is taken to be 0.287 kJ/kg K. If the compression ratio is 15/1, and the temperature at the end of compression is 870 K, find at what percentage of the stroke the combustion is completed.
