How long can an O2 tank with 1000 psi deliver gas at a fresh flow of 2L/min?

To determine how long an O2 tank with 1000 psi can deliver gas at a flow rate of 2 L/min, it's essential to understand the capacity of standard oxygen tanks. Generally, a full standard oxygen tank contains about 2200 psi and has a volume of approximately 660 liters of oxygen.

First, consider the flow rate. At a fresh flow of 2 L/min, we can calculate the total time the tank can deliver oxygen as follows:

1. Determine usable gas in the tank at 1000 psi:

• A tank that is full at 2200 psi delivers about 660 liters.

• The total liter capacity of the tank in proportion to the psi:

[

\text{Liters available} = \text{Total liters} \times \left(\frac{\text{Gas pressure}}{\text{Full tank pressure}}\right) = 660 \times \left(\frac{1000}{2200}\right) \approx 300 \text{ liters}

]

2. Calculate delivery time:

• At a flow rate of 2 L/min, we can determine how long the available gas will last:
