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
O2 is stored in liquid form. It has an expansion ratio of 1:861 at STP. So a 1 liter bottle of LO2 will provide 861 liters of O2 gas.
