Step 1

To calculate the stoichiometric AFR, we need to know the fuel being used. Let's assume it is a hydrocarbon fuel like methane (CH4). The stoichiometric AFR for methane is 17.2:1. This means that for every 17.2 parts of air, we need 1 part of methane. Show more…

The percentage of excess air is 12.45%. The percentage of excess air is 44.4%. The percentage of excess air is 29.3%. The percentage of excess air is 2.9%. The percentage of excess air is 7.22%. The temperature is 20Â°C and the pressure is 100 kPa using stoichiometric air. The percentage of excess air is 4.32%. The percentage of excess air is 1.38%. The percentage of excess air is 2.87%. The percentage of excess air is 1.09%. To determine the parts 7 and 8.
