Answer to Question 1

ANS: B
Amount of time left in cylinder = (cylinder pressure  cylinder factor)/flow rate of gas (li-ters/minute). G factor = 2.41. Time to use 2000 psig = (2000  2.42)/5 = 964 minutes/60 = 16 hours. 2000 psig /16 hours = X psig/6 hours. X = 750 psig will be used in 6 hours at 5 L/min.

Answer to Question 2

ANS: C
The reservoir stores a mixture of liquid and gaseous oxygen. The vaporizer acts as a heat ex-changer where heat is absorbed from the environment and used to warm the liquid oxygen to room temperature, thus forming gaseous oxygen.
