2 hours and 30 minutes at 4.5 liters
2 hours and 15 minutes at 5 liters
Because they're not used in an 1:1 ratio. One cylinder is made bigger so that they'll still end up empty at about the same time.
yes if the oxygen is in liquid form.
60 grams
It should weigh 45kg + the TARE weight of 36.6kg for the bottle = 81.6kg when full. The WC (water capacity) of the bottles are 109.8kg and LPG weighs 41% of water = 45kg. This is a good check to see if you are being ripped off by your gas supplier.
Using a pressure guage to determine the pressure of the gas inside, as thepressure decreases you can tell that it is getting empty. Another way is if you know the weight of the empty cylinder weigh the cyleinder and the difference gives you how much nitrogen is in it.
Gas cylinders weigh about the same whether full or empty.
A full cylinder is heavier than empty. The cylinder is filled by weight.

The empty cylinder weighs upto 20 kgs
100 cc is equal to 0.1 liter. Regardless of what's in them. Even if they're empty.
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....
45 years ago i was working for a company and had to use and move big oxygen and nitrous oxide cylinders around. when a cylinder was empty i used to write with chalk MT on the cylinder .... was this the start of text talk ?
there are no safeties on revolvers. keep cylinder under hammer empty or keep cylinder empty. then gun is safe....................
The cylinder should be evacuated
What ever was in the cylinder had weight of its' own. When the cylinder was emptied, only the weight of the cylinder was left.
yes
1 cubic meter = 1,000 liters, regardless of what's in it. Even if it's empty.
