Chapter 10, Problem 10.18P
10.18. A 40.0-ft3oxygen tent initially contains air at 68°F and 14.7 psia. At a time t = 0 an enriched air mixture containing 35.0% v/v O2and the balance N2is fed to the tent at 68°F and 1.3 psig at a rate of 60.0 ft3/min, and gas is withdrawn from the tent at 68°F and 14.7 psia at a molar flow rate equal to that of the feed gas.
- Calculate the total lb-moles of gas (O2+ N2) in the tent at any time.
