Calculate the number of minutes remaining in an oxygen tank based on tank size, pressure and continuous flow rate.The following equation is used to determine the remaining duration of flow:

Duration of Flow = Oxygen Tank Conversion Factor * (Remaining Tank Pressure - Safe Residual Pressure) / Continuous Flow Rate

Oxygen Cylinder Conversion Factors
• D Tank = 0.16
• E Tank = 0.28
• G Tank = 2.41
• H/K Tank = 3.14
• M tank = 1.56

Safe Residual Pressure = 200psi
