A cylinder of oxygen, used as medical aid, has a volume of 16 L. It is filled to a pressure of `1.37 x× 10^(7) Nm^(–2)` above the atmospheric pressure at room temperature of 300 K. When in use, the flow rate at atmospheric pressure is `2.4 L//"min"`. How long will the cylinder last? Atmospheric pressure is `10^(5) Nm^(– 2)`.
