(no outgassing/leaks)

| Parameter | Unit | Value | | --- | --- | --- | | System Volume (V) | L | 100 | | Gas Load (Q) | L/s | 10 | | Desired Vacuum Level (P) | mbar | 10 | | Pumping Time (t) | seconds | 600 | | Required Pump Capacity (S) | L/s | =(100*(10/600))+10 = 11.67 | vacuum pump capacity calculation xls
