A mixture of methane and air is capable of being ignited only if the mole pecent of methane is between 5% and 15%. A mixture containing 9.0mole% methane in air flowing at a rate of 700.kg/h is to be diluted with pure air to reduce the methane concentration to the lower flammability limit. Calculate the required flow rate of air in mol/h and the percent by mass of oxygen in the product gas. (note Air may be taken to consist...
