1. Hydrogen (H2) enters a combustion chamber with a mass flow rate of 5 lb/h and burns with air entering at 858F, 1 atm with a volumetric flow rate of 75 ft3/min. Determine the percent of theoretical air used.
2. Methyl alcohol (CH3OH) burns with 200% theoretical air, yielding CO2, H2O, O2, and N2. Determine the
(a) balanced reaction equation.
(b) air-fuel ratio on a mass basis.
(c) molar analysis of the products.
