Oxygen Cylinder Volume Formula:
| From: | To: |
The Oxygen Cylinder Volume Calculator estimates the usable oxygen volume in a pressurized cylinder based on pressure and cylinder capacity. This calculation is essential for medical, diving, and industrial applications where accurate oxygen supply management is critical.
The calculator uses the oxygen volume formula:
Where:
Explanation: The formula converts pressurized gas volume to usable volume at atmospheric pressure, accounting for the compression factor.
Details: Accurate oxygen volume calculation is crucial for patient safety in medical settings, dive planning in scuba diving, and industrial process control where oxygen supply duration must be precisely determined.
Tips: Enter cylinder pressure in psi and cylinder capacity in liters at STP. Both values must be positive numbers. The result shows usable oxygen volume in liters at atmospheric pressure.
Q1: What is STP and why is it used?
A: STP (Standard Temperature and Pressure) is 0°C and 1 atmosphere, providing a standardized reference point for gas volume measurements.
Q2: Why divide by 14.7?
A: 14.7 psi represents one atmosphere of pressure, converting pressurized gas volume to equivalent volume at atmospheric pressure.
Q3: Can this calculator be used for other gases?
A: While the formula works for any gas, oxygen-specific safety factors and regulations should be considered for medical and diving applications.
Q4: How accurate is this calculation?
A: The calculation provides theoretical volume. Actual usable volume may vary due to temperature changes, regulator efficiency, and safety margins.
Q5: What are typical cylinder capacities?
A: Medical oxygen cylinders typically range from 200-3000 L at STP, while diving cylinders are usually 2000-3000 L at STP capacity.
