What is the volume of gas in ft3 contained in a bank of cylinders at a pressure of 2950 psi?

To determine the volume of gas in cubic feet (ft³) contained in a bank of cylinders at a specific pressure, it is essential to apply the ideal gas law or utilize standard conversion factors based on the conditions and properties of the gas being used, typically air or pure gas like oxygen or nitrogen in diving applications.

The calculation begins by recognizing that at standard temperature and pressure (STP), one mole of an ideal gas occupies approximately 22.4 liters, which can be converted to cubic feet utilizing conversion factors. The relationship between pressure, volume, and gas type can be expressed through formulas derived from the ideal gas law.

Given the pressure of 2950 psi, you would typically use standard charts or equations that relate cylinder pressure and volume for the specific gas. In a well-controlled system like diving gases in cylinders, the volume can be approximated using established tables or empirical formulas unique to the gas type at the given pressure.

The calculated value of 1707 ft³, which aligns with option A, indicates that this is the volume of gas available at that pressure in the cylinders based on standard conditions and fills. This volume reflects the total amount of gas that can be available for use under certain operational parameters, making it crucial for determining how long
