In order to get maximum calorific output, a burner should have an optimumfuel-to-oxygen ratio which corresponds to 3 times as much oxygen as is required theoretically for complete combustion of the fuel. A burner which has been adjusted for methane as fuel (with x litre/hour of CH_4 and 6x litre/hour of O_2 ) is to be readjusted for butane, C_4H_10 . In order to get the same calorific output, what should be the rate of supply of butane and oxygen? Assume that losses due to incomplete combustion, etc., are the same for both fuels, and that the gases behave ideally. Heat of combustion:

Answer» Solution :VOL. of `C_4H_10` required per `H = (804)/(2878) L` Vol. of `O_2` required per h`((804x)/(2878)) XX 13/2 xx 3L` `C_4H_10 = 0.28 x L// h` `O_2 = 5.48x L//h`
