Final answer:
The oxygen tank with a pressure of 2000 psi and a factor of 0.16 will last approximately 26.67 minutes at a flow rate of 12 LPM.
Step-by-step explanation:
The student is asking about how long an oxygen tank with a pressure of 2000 psi and a conversion factor of 0.16 will last if it is being used at a rate of 12 liters per minute (LPM). To determine the duration for which the oxygen tank will last, the following calculation can be done:
Duration (minutes) = Pressure (psi) * Tank Factor / Flow rate (LPM)
In this case, the calculation will be:
Duration = 2000 psi * 0.16 / 12 LPM
Duration = 320 / 12
Duration ≈ 26.67 minutes
Therefore, the oxygen tank will last for approximately 26.67 minutes when used at a flow rate of 12 LPM.
