Final S=Seff×1.25Final cap S equals cap S sub eff end-sub cross 1.25 Structuring the Vacuum Pump Capacity Calculation XLS
The corrected capacity is: $S_corrected = S_required / (k_1 \times k_2)$
FINAL PUMP SIZING: Corrected Speed w/o Conductance (m³/h) =B13 B8 -> 732.8 Effective Speed with Conductance (m³/h) =1/( (1/B14) + (1/(B7/3.6)) )? (unit careful) Simpler: Required Pump Nominal Speed (m³/h) =B14 1.2 (20% conductance reserve) -> 879.4
"Okay," Lucas said, confidence returning. "It will take 15 minutes to pull the vacuum, assuming the leakage doesn't get worse. But what about the water vapor flash? The initial flash will be massive."
