Volume Calculator for Compressed Oxygen

How to Use the Calculator

1. Enter the volume of your oxygen cylinder in liters (e.g., 2.0 for a standard D cylinder).
2. Enter the initial pressure in the cylinder in bar (e.g., 200 for a full cylinder).
3. Enter the final pressure in the cylinder in bar (e.g., 150 for a cylinder with 50 bar remaining).
4. Click the "Calculate" button to determine the volume of oxygen remaining in the cylinder.

Working Principle

The calculator uses the formula: Volume of Oxygen = (P₁ - P₂) × V × 10⁻³, where P₁ is the initial pressure, P₂ is the final pressure, and V is the cylinder volume. This formula calculates the volume of oxygen in liters remaining in the cylinder based on the pressure difference and cylinder size.

Example

If you have a 2.0-liter oxygen cylinder with an initial pressure of 200 bar and a final pressure of 150 bar, the calculator will determine that there are approximately 1.0 liters of oxygen remaining in the cylinder.
