The gauge on a G cylinder of O₂ reads 400 psig. About how long would the contents of this cylinder last, until completely empty, at a flow of 5 L/min?

Question

Quizplus · Accepted Answer

A G cylinder of O2 typically contains about 5300 liters when full. At 400 psig, it is approximately 1/4 full, so it contains about 1325 liters. At a flow rate of 5 L/min, it would last approximately 265 minutes, which is about 4 hours and 25 minutes. However, considering the options, the closest is 3 hours 10 minutes, which might be due to a different assumption about the cylinder's capacity or pressure reading.
