INTERMEDIATE CALCULATIONS: Volume/Time ratio (L/s) =B3/B6 -> 33.33 Ln(Pi/Pf) =LN(B4/B5) -> 5.31 Ideal Speed (L/s) =B10 B11 -> 177.0 Ideal Speed (m³/h) =B12 3.6 -> 637.2 Convert to m³/h: ( 177 \times 3

Build it step by step as shown above, validate with known cases, and you’ll never oversize or undersize a pump again. For the remaining 10% of critical high-vacuum or high-throughput applications, let your XLS be the starting point for deeper simulation. Most engineering forums (Eng-Tips, Reddit r/AskEngineers) share open-source versions. Alternatively, build yours from the logic above in 30 minutes – and gain mastery of vacuum system design in the process. Alternatively, build yours from the logic above in

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
