How to Use This Calculator
- Enter the number of crew members and their daily oxygen consumption in kg/person/day.
- Set the oxygen generation method (electrolysis, chemical, stored).
- Input system efficiency percentage and power available in watts.
- Review the daily oxygen production rate in kg and power consumption.
- Size the backup stored oxygen supply to cover at least 48 hours of failure.
