: Calculated using sonic velocity equations for compressible fluids. Nozzle Outlet Area ( cap A sub 2 : Based on the expansion needed to reach suction pressure. Ejector Throat Area ( cap A sub 3
In the world of fluid dynamics and process engineering, the ejector (or eductor) is a deceptively simple device. With no moving parts, it uses a high-pressure motive fluid to entrain, compress, or pump a secondary low-pressure fluid. From vacuum distillation in oil refineries to chemical dosing in water treatment, ejectors are indispensable. ejector design calculation xls
