An average d size tank will last for about 20 min with a non re breather at 15 lpm
Duration = ((current pressure -200) x tank factor) / flow rate tank factors are M=1.56 E=0.28 D=0.16

If the nitrogen and oxygen were not replaced in the atmosphere how long would your present supply of gases would last?
If you are the only one living on earth it would last for your lifetime.
How long does a 2 liter tank of oxygen last?
No way of telling w/o knowing the pressure in the tank at the start and the flow rate.
If the nitrogen and oxygen were not replaced in the atmosphere how long would the present supply of gases last?
It would run out pretty fast. Humans would quickly consume all of the oxygen that is available and it would be all gone.
Does nitrous oxide expire?
No, this compressed gas has a long, long shelf life. But the cylinder it is smooshed into has a code date on it. Under nominal storage conditions, it should last decades, but corrosion can affect the cylinder or the valve. And should the tank be emptied, it cannot be refilled if the cylinder's "useful life" has passed. It will have to be hydrostatically tested and recertified. We know that nitrous oxide (N2O) is pretty stable stuff under nominal conditions. It stays the way it is when it is bottled up.

How long will a ml6 oxygen cylinder last?
An ML6 oxygen cylinder, when "charged" to normal pressures, holds 170 liters of oxygen. How long that will last depends on a number of factors. If the flow is set to 2 liters per minute continuous then it will last less than 1 and 1/2 hours. If an oxygen conserving device is used (they give the gas in pluses when breaths are taken) it can last over 4 hours.
How long will a size h oxygen cylinder last?
This will depend upon the gas flow rate. A size E oxygen cylinder in the UK contains 680 litres of compressed gas. At a flow of 10L/min for medical emergency use the cylinder will therefore last 68 mins. However if used at 6L/min it will last nearly 2 hours. In the US we use PSIG (gauge level). at full a tank is about 2200 PSI on any given tank size, and the E cylinder has a tank factor of 0.28. So you take take the PSI and multiple it by by the tank factor and divide that number by the flow rate. So at full, 2200 x 0.28 = 616 and dvided that by the flow rate. The final number is the total number of minutes at the given flow rate. So at 2 liters per minute (2 lpm) a completely full E cylinder will last 308 minutes or 5.13 hours (divide total minutes by 60 to get hours). 140 minutes at 4lpm, and so on. You deffinetly want to call your oxygen supplier well before the guage gets to the red. With most guages the very start of the red line (the end farthest from empty) is around 500 PSI. A good rule of thumb is to round down to the nearest whole hour when figuring duration. So when I've needed to I look at 5.16 hours and say 5 hours. If you do run out or are into the red already, call 911 (or your local emergency service), all ambulances carry oxygen and better to have them arrive and use their O2 than to call your oxygen service because ambulance should be able to get their faster. Remember, at the very beginning of red (500 PSIG) a E cylinder will only last 140 divided by flow rate...so 70 minutes at 2lpm, 35 minutes at 4lpm, etc. Dont risk it, when in red, call 911 first, then your oxygen supplies...that is as long as you dont have any other cylinders to use. common tank factors: H Cylinder factor is 3.14 D cylinder factor is 0.16 (typical portable oxygen size) * in the USA, all oxygen tanks, when completely full, are 2200 PSI, if you know the tank factor, you can easily compute the duration. Calculating liquid oxygen is a whole nother ball of wax....
How long can oxygen last?
it can last for as long as you can hold your breath. after that time you have 3 minutes before you pass out.
How long will oxygen last At current rate of burning?

Why can a person last 1 minute without oxygen?
A person can last 4 minutes without oxygen, longer in extreme cold. It takes that long for the body to use up the oxygen in the blood.
What do you call a long cylinder?
A cylinder? A cylinder is still a cylinder regardless of how long it is.
How long does 22 trees worth of of oxygen last per-day?

How long will 115 cu ft of oxygen last at 25000 ft?
20 minutes
Is argon lethal?
It is not toxic but because it takes up space it can displace oxygen and we can't last long breathing an atmosphere without oxygen.
How long would a fire last with a limited amount of oxygen?
The is not enough information to answer this. We need to know what is burning, how much, and how fast, and how much oxygen we have.
How long will a size G oxygen cylinder last?
Depending on the flow rate. A G tank holds 5,300 liters of Oxygen. so just divide that buy the rate you are setting it to flow at. A non-rebreather at 15 lpm should last you close to 6 hrs. normally though the tank should be refilled before it gets down to around 200 psi, just to be safe.
How long does a flame last?
Until the fuel or oxygen is all consumed, whichever comes first.
