A document that outlines the structure of a widely used Excel sheet for entrainment and area ratios.
Use the law of conservation of momentum within the mixing chamber to find the velocity of the mixed stream:
When building and executing your calculation spreadsheet, validate your outputs against industrial field behaviors to prevent design failures: ejector design calculation xls
Therefore, the throat diameter is: [ D_t = \sqrt\frac4 \times A_t\pi \approx 0.00433 \text m = 4.33 \text mm ]
The model assumes both motive and suction gases behave as ideal gases, which is a reasonable approximation at the low pressures typical in the suction and mixing chambers. A document that outlines the structure of a
Once your spreadsheet is developed, it is critical to validate it against known data.
An ejector consists of four main parts:
Before diving into spreadsheet formulas, we must establish the core physics.
