A vehicle burns gasoline (density = 0.79 kg/liter) at a rate of 7.6 liters per hour. Although gasoline is a mixture of many chemicals, for simplicity assume it has the formula of octane, C8H18
What is the required air flow rate in molar units (kmol/hr), in mass units (kg/hr) and in standard volume units (standard m3 /hr) for air fed in stoichiometric proportion?
Determine the flowrate (kmol/hr) and composition (mol fraction) of the exhaust gases if 25% excess air is fed with the gasoline. For purposes of this problem, only carbon dioxide and water (no carbon monoxide) is produced in the reaction and all of the gasoline is consumed.
