Answer to Question 1

ANS: C
Amount of time left in cylinder = (cylinder pressure cylinder factor)/flow rate of gas (li-ters/minute). K factor = 3.14. Time to use 800 psi = (800 3.14)/7 = 358.8 min/60 = 5 hours 59 minutes.

Answer to Question 2

ANS: B
Amount of time left in cylinder = (cylinder pressure cylinder factor)/flow rate of gas (li-ters/minute). E factor = 0.28. Time to use 900 psig = (900 0.28)/10 = 25 minutes.
