Question

You have an oxygen tank with 2000psi and a factor of 0.16. How long will the tank last at 12LPM?

Answer 1

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.

Answer 2

24 minutes.

Step-by-step explanation:

Formula:

((tank pressure - 200) x factor) / LPM = Lasting time

200 represents the safe residual for maintaining the tank. As per the rule that oxygen tanks should be replaced when reaching the 200 psi mark.

Plugging in variables we get

• ((2000 - 200) x 0.16 / 12 = x

Simplifying,

1. 1800 x 0.16 / 12 = x
2. 288 / 12 = x
3. 24 = x

Your oxygen tank will last 24 minutes at 12 Liters per minute
