Ejector Design Calculation Xls

Cells calculating critical pressure ratio, throat velocity, and cross-sectional area.

Correct your suction gas flow rate if you are pumping gases other than air or water vapor by implementing the HEI molecular weight correction factor. ejector design calculation xls

): Calculated based on motive gas flow rate, pressure, and temperature. Cells calculating critical pressure ratio

Use the following isentropic expansion formula to find the throat diameter ( Dtcap D sub t ejector design calculation xls

Use either:

The goal here is to determine the motive nozzle throat diameter (Dₜ) based on the motive fluid properties and flow rate.
