Size an afterburner and specify the flow rate of methane neededto control 8000 cfm of air from a paint-drying oven. The ovenexhaust gases are available at 250 degrees F. Assume that thedesign temperature and residence time have been established as 1300degrees F and 0.6 seconds respectively. The type of burner used inthe process requires outside air at a mass ratio of 12:1
