- 0.4
- Measured unrecovered gas fraction
- 0.1
- Run duration (hours)
- 8

Try another scenario
- Packages per hour (count/hour)
- 1500
- Fill gas volume per package (litres)
- 0.5
- Measured unrecovered gas fraction
- 0.2
- Run duration (hours)
- 6
- Usable cylinder gas volume at same reference conditions (litres)
- 4000
- Gross gas requirement (litres)
- 5625
- Whole cylinders required (count)
- 2
Calculation method
Calculation method
Gross gas requirement (litres)
Throughput×fill volume×duration/(1−loss fraction).
Whole cylinders required (count)
ceil(gross requirement/usable cylinder volume).

Assumptions & limits
Assumptions & limits
- User-specified fill-gas volume and measured loss; no atmosphere composition recommendation. Supported limits: All numeric inputs and computed intermediates must remain finite. Supported numeric input magnitude is zero or 1e-12 through 1e12 in absolute value; reject values outside this bounded range. All lists/JSON record tables are limited to 100 records unless a stricter bound is stated; reject malformed record arity and wrong member types. Loss fraction in [0,1); volume units share identical user-stated pressure/temperature reference; cylinder usable volume>0.
