Answer to Question 1

ANS: D
Amount of time left in cylinder = (cylinder pressure  cylinder factor)/flow rate of gas (li-ters/minute). 2200  400 = 1800 psig (the amount of gas that will be used). (1800  0.28)/2 = 252 minutes/60 = 4 hours 12 minutes.

Answer to Question 2

ANS: B
Before 1997, nitric oxide was supplied in cylinders with a volume capacity of 152 cubic feet. It is now supplied in smaller cylinders (82 cubic feet) with 626 CGA valve outlets.
