Cylinder Fill Capacity at 63% fill station uptime: a worked example

Suppose fill station uptime falls to 63%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate good fire suppression cylinder filling output from cylinders per fill cycle, available cycles, fill station uptime, and accepted fill yield.

The inputs for this scenario

  • Cylinders filled per cycle: 8 cylinders / cycle (held at the documented default)
  • Available fill cycles: 42 cycles (held at the documented default)
  • Fill station uptime: 63 % (the input this scenario stresses; the baseline uses 88)
  • Accepted fill yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross cylinder fill capacity = cylinders filled per cycle × available fill cycles.
  • Good output capacity works out to 205 units at these inputs, and this is the headline figure for the scenario.
  • Gross capacity before uptime and yield works out to 336 units at these inputs.
  • Availability loss works out to 124 units at these inputs.
  • Reject or rework allowance works out to 6.35 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where fill station uptime sits at 88% and the headline result is 287 units, this scenario comes in 28.41% below the baseline at 205 units.
  • It multiplies cylinders per cycle by available cycles for gross capacity, then applies uptime and accepted yield to give good, ship-ready output. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Good output capacity: 205 units (headline result)
  • Gross capacity before uptime and yield: 336 units
  • Availability loss: 124 units
  • Reject or rework allowance: 6.35 units
