Q3. A fuel has a mass analysis of 81.6% carbon and 18.4 % hydrogen.

It is burned at a pressure of 2.5 bar with an air fuel ratio of 14:1. The combustion gasses are then cooled at constant pressure to a temperature of 39°C.

Calculate EACH of the following for 1 kg of fuel:

(a) the volumetric analysis of the combustion gas before cooling; (10)

(b) the mass of water removed from the gas during the cooling process. (6)

Note: atomic mass relationships H =1, C = 12, O = 16, N = 14.

air contains 23.3% oxygen by mass.
