A military vehicle burns gasoline at a rate of 2 gallons (13.2 lbm) per hour. Although gasoline is a mixture of many chemicals, for simplicity assume it has the formula C8H18. What is the required air flow rate (lbm/h) assuming it is added stoichiometrically? For desert operations, this military vehicle is fitted with a special device that condenses moisture out of the engine exhaust. What is the maximum amount of water (lbm/h) that could be recovered?
