Problem 3: Wrong Gas Properties (Ideal Gas Assumption Fails)

Symptom: Spreadsheet works for air but gives nonsense for steam or heavy hydrocarbons.
Fix: This write-up provides a technical overview and operating

2. The "Fixed" Efficiency Trap Many simple spreadsheets assume a constant mixing efficiency (e.g., 0.8 or 80%). In reality, efficiency varies with flow rates. A "Fixed" efficiency input allows the engineer to tune the spreadsheet based on historical vendor data, making the tool more accurate for future predictions. Problem 3: Wrong Gas Properties (Ideal Gas Assumption

) does not exceed the "critical discharge pressure." If it does, the shockwave will move back into the throat, and the ejector will stop suctioning (breaking the vacuum). 4. Structuring Your XLS for Accuracy

Determines the amount of motive steam required to move the suction load. Nozzle Sizing: Calculates the throat diameter ( ) based on the sonic flow of motive steam. Mixing Chamber Design:
