A gas contains 65.0wt% methane, 10.00wt% ethane, 20.0wt% ethylene, and the balance water. Calculate the molar composition of this gas on both a wet and a dry basis and the ratio ( molH2O/moldrygas). molH2O/mol dry gas: If 100.0kg/h of this fuel is to be burned with 30.0% excess air, what is the required air feed rate? kmol/h What is the required feed rate if the combustion is only 75.0% complete? kmol/h
