What is the psi range for low-pressure liquid oxygen (LOX)?

The psi range for low-pressure liquid oxygen (LOX) is specifically defined to ensure safe handling and operation within various aircraft systems. The correct range is between 70 to 90 psi, which reflects the typical operational parameters for LOX systems. This pressure range allows for effective pressurization and delivery of LOX while minimizing the risks associated with both low and high-pressure scenarios.

Understanding these psi ranges is crucial for maintaining the integrity and functionality of oxygen systems on aircraft. If the pressure were to fall below 70 psi, it could indicate a potential issue with the containment or delivery system, whereas exceeding 90 psi could pose risks of over-pressurization and possible failure of components. Therefore, this range is established based on safety, efficiency, and performance metrics deemed necessary for effective aircraft operation.
