A mixture of methane and air is capable of being ignited only if the mole percent of methane is between 5% and 15%. A mixture containing 9.0 mol% methane in air that is flowing at a rate of 700 kg/hour is to be diluted with pure air to reduce the methane concentration to the lower flammability limit. a) What is the required flow rate in kmol/hour of pure air needed to lower the methane concentration to 5.0 mol%? b) What is the flow rate of oxygen in kg/hour in the product gas with 5.0 mol% methane?

Question
A mixture of methane and air is capable of being ignited only if the mole percent of methane is between 5% and 15%.
A mixture containing 9.0 mol% methane in air that is flowing at a rate of 700 kg/hour is to be diluted with pure air to reduce the methane concentration to the lower flammability limit.
a) What is the required flow rate in kmol/hour of pure air needed to lower the methane concentration to 5.0 mol%?
b) What is the flow rate of oxygen in kg/hour in the product gas with 5.0 mol% methane?
