Benzaldehyde is produced from toluene in the catalytic reaction

C₆H₅CH₃ + O₂ C₆H₅CHO + H₂O

Dry air and toluene vapor are mixed and fed to the reactor at 350.0 F and 1 atm. Air is supplied in 200.0 % excess. Of the toluene fed to the reactor, 13.0 % reacts to form benzaldehyde and 1.70 % reacts with oxygen to form CO₂ and H₂O. The product gases leave the reactor at 379 F and 1 atm. Water is circulated through a jacket surrounding the reactor, entering at 80.0 F and leaving at 105 F. During a four-hour test period, 34.3 lb_m of water is condensed from the product gases. (Total condensation may be assumed.) The standard heat of formation of benzaldehyde vapor is 17,200 Btu/lb-mole; the heat capacities of both toluene and benzeldehyde vapors are approximately 31.0 Btu/(lb-mole F); and that of liquid benzaldehyde is 46.0 Btu/(lb-moleF).

Calculate the volumetric flow rates (ft³/h) of the combined feed stream to the reactor and the product gas.
