Answer to Question 1

ANS: D
Amount of time left in cylinder = (cylinder pressure  cylinder factor)/flow rate of gas (li-ters/minute). (2000  0.28)/4 = 140 minutes to use up 2000 psig. Therefore, 2000 psig/140 min = X psig/1 minute X = 14.3 psig/min  45 minutes = 642.8 psig.

Answer to Question 2

ANS: D
Amount of time left in cylinder = (cylinder pressure  cylinder factor)/flow rate of gas (li-ters/minute). E size factor = 0.28. A simple mask should run at a minimum of 5 L/min. There-fore, (1600  0.28)/5 L/min = 448/5 = 89.6 minutes.
