Flow by pressure
The flow applies to a pressure of 7 bar and a temperature of +20 °C. At a higher pressure, it is multiplied by the correction factor; from 100 bar it is 12:
| Pressure (bar) | 7 | 25 | 40 | 64 | 100 | 250 | 420 |
|---|---|---|---|---|---|---|---|
| Flow (l/min) | 667 | 2,001 | 3,335 | 5,336 | 8,004 | 8,004 | 8,004 |
