QUESTIONS AND ANSWERS
Since nitrous is partial liquid, how do you "technically" tell how much is left in a tank? -
Answer-weigh it : there is no partial pressure relationship; partial pressure remains the
same all the way until al the liquid is gone
No part of a cylinder should ever be subjected to a temp. above ____ C or below _____
C. - Answer-54; -7
Always keep cylinder valve closed when not using because if the pipeline fails, the vent
will deplete the cylinder (with/without) alarming - Answer-without
Valves should always be opened (slowly/fast)? - Answer-Slowly: Gas law state rapid
recompression in this space will generate large amounts of heat. potential combustion
part 1: Formula to calculate how long the amount in a cylinder will last? - Answer-
Capacity/Service pressure= Tank factor
for O2
660/1900=0.35
part 2: Formula to calculate how long the amount in a cylinder will last once you have
your tank factor? - Answer-Tank factor x gauge pressure = Liters remaining.........
then your answers and divide by flow rate ( however many liters/minute) to see how
many minutes you have left.
oxygen concentrators produce between ____% and ____% o2 concentrations after the
process is over? - Answer-90%; 96%
In oxygen concentrators, which gas is not trapped by the molecular sieve and is
concentrated like oxygen? - Answer-Argon
What concentration can Argon reach? - Answer-above 5%
With oxygen concentrators, if oxygen is 93% is added to a circle system with low fresh
gas flow, the ________ may accumulate - Answer-argon
The accumulation of argon has not been found to be a problem if the fresh gas for is
above _________ L/min - Answer-0.5........ No effects of exposure to low concentrations
of argon anyways
