What is the maximum amount of liquid oxygen the LOX converter can hold?

• A. 15 Liters
• B. 20 Liters
• C. 25 Liters
• D. 30 Liters

Answer: (C)

The maximum capacity of a LOX converter is tied to the system’s design limits and safety margins for storing cryogenic liquid oxygen. A fixed, specified volume ensures a predictable boil-off rate, manageable venting, and safe pressure control during operation. In this context, 25 liters is the design target because it provides enough LOX for the system’s needs without pushing the vessel beyond its structural and safety limits. Using less would risk running out during operation or requiring more frequent re-supply, while more would increase weight and potential boil-off losses beyond safe margins. Hence, 25 liters is the correct maximum. The other values would either understate or exceed the intended design capacity and safety requirements.
