Step-by-Step: Fixing a Broken Ejector Design XLS

1. Check all named ranges – Formulas often use =NozzleArea – ensure those names still point to valid cells.
2. Replace hardcoded values (like 1.4 for γ) with cell references to inputs.
3. Add a status cell that flags if any input is out of typical range (e.g., P discharge > P motive).
4. Validate with a known case: Run the spreadsheet for air (γ=1.4) with published data from Power’s “Ejector Design” (1950s still valid).
5. Lock input cells to prevent accidental edits, but unlock formulas so you can trace errors.
