Web26 de mar. de 2024 · Example. For example, let’s say you have an E cylinder with a pressure of 2200 psi and a flow rate of 2 L/min. The duration of the oxygen tank can be calculated as follows: Duration (minutes) = (2200 psi x 0.28) / 2 L/min. = 308 minutes. Therefore, this oxygen tank will last for approximately 5 hours and 8 minutes.
