Solution:The combustion reactions for propane and butane are: (a) Stoichiometric Air RequirementOn the basis of 1 volume of the fuel gas, the propane content requires0.7 Ã (5 + 18.8) = 16.7 vols airand the butane requires0.3 Ã (6.5 + 24.5) = 6.3 vols airHence the stoichiometric air-to-fuel ratio is 23:1.
