Problem # 1 : The composition of a gaseous fuel is CH4 60, C2H6 30 and N210 % by volume. The fuel is burned with 110 % theoretical air. The combustion sir is supplied at 100 kPa abs and 30 C, and 55 percent relative humidity. Calculate the air/fuel ratio and the analysis of the wet and dry products of combustion. Hint: Nwater= ( Py Ndry air / (P-Pv))
