    Problem.

    Ethyl alcohol has the chemical formula C2H6O. Calculate the stoichiometric air/fuel ratio by mass and the corresponding wet gravimetric analysis of the products of combustion.

    Solution:

    a) Finding the A/F ratio

    We will use following notations:

    Mx = molar mass (kg/kmol)
     = volumetric ratio nitrogen/oxygen in the air composition
    Mf = molar mass of the fuel (kg/kmol)

    We consider the stoichiometric burning reaction of ethyl alcohol:
    ( 1)
    The above coefficients will be found by simple atomic balance analysis:
    - for carbon:  = 2
    - for ...

    Solution Summary

    ETHYL ALCOHOL HAS THE CHEMICAL FORMULA C2H6O. CALCULATE THE STOICHIOMETRIC AIR/FUEL RATIO BY MASS AND THE CORRESPONDING WET GRAVIMETRIC ANALYSIS OF THE PRODUCTS OF COMBUSTION.
