I work at a hospital and I noticed that the oxygen cylinders are labelled as containing 630 litres of oxygen. (Yes yes, suuuper busy day at work) Similarly the flow rate out of the cylinder is set in L/min. This piqued my interest as I know a litre is a set volume, yet clearly the cylinder was not that large. So what is a litre in this case? …and why is it this way?
In: Physics
Probably much easier to calculate everything based on the literage than the mass (about 27 kilos) which isn’t very useful. That’s 630 L is at atmospheric pressure meaning they have squeezed all of that volume under pressure into the bottle to store and transport it.
