[ S_required = \fracQ_totalP_base ]

Conductance in L/s → convert to m³/h (multiply by 3.6) before combining with m³/h pump speed.

| Pump type | Correction factor (K) at 10 mbar | |-----------|----------------------------------| | Rotary vane | 0.95 | | Dry screw | 0.90 | | Roots blower (backed) | 1.15 | vacuum pump capacity calculation xls

A pure ( \ln(P_i/P_f) ) calculation is a starting point, but real systems add complexity. Your XLS calculator must account for:
