In order to get maximum calorific output, a burner should have anoptimum fuel to oxygen ratio which corresponds to 3 times as muchoxygen as is required theoritically for complete combustion of the fuel. A burner which has been adjusted for methane as fuel (with Xlitre/ hour of CH4 and 6X litre/ hour of O2)is to be readjusted for butane, C4H10. Inorder to get the same calorific output, what should be the rate of supply of butane and oxygen? Assume that losses due to incompletecombustion, etc are same for both the fuels and gases behaveideally.
Heats of combustion : CH4 = 809kJ/ mol,C4H10 = 2878 kJ/ mol.
