In a fixed design, the area of the mixing section determines the maximum suction flow before the unit reaches a "choked" state. Step 3: Diffuser Recovery
Fixed ejectors are notoriously sensitive to discharge pressure. A 5% increase in back-pressure can sometimes result in a 50% loss in suction capacity. Conclusion ejector design calculation xls fixed
Where velocity is converted back into pressure (static head) to reach the discharge requirement. In a fixed design, the area of the
Create a table that shows how the suction vacuum changes if the motive steam pressure drops by 10%. 5. Common Pitfalls in Fixed Ejector Design In a fixed design
