- What’s the volume in a tank
(E-cylinder) when the pressure reads 500PSI?
500 psig = 23% full
2200 psig
- How many hours will an
H-cylinder last if it runs at 5 liters/min from full?
2200 x 3 = 1320 min/60min 1hr = 22 hrs
5 LPM
- How long will an H-cylinder
last when it reads 1000PSI? Flow = 8LPM
1000 psig x 3 = 375 min/60 min/hr = 6.25 hrs
8 LPM
- How long will an E-cylinder
run if its liter flow is 1.5 liters/min and the pressure 1800 PSI?
1800 x .3 = 360 min/60min/hr = 6hrs
1.5 LPM
- How long (with a G-cylinder ) will oxygen run if it is set on 1liter/min
and the pressure reads 650 PSI? (factor for G=2.41)
650psig x 2.41 = 1566.5 min/60
min/ = 26.1 hrs
1 LPM
