DETERMINE EDUCTOR PLACEMENT • Little agitation occurs below the level of the eductor, so eductors should be positioned as close as possible to the bottom of the tank for maximum liquid turnover • If settling cannot be tolerated, install the eductors at 1' (. This method deals with the gases in terms of weight of flow in a given period of time. The available water pressure is 60 psi. Experimentally validated simulations were used to determine the effect of nozzle eductor. Semi-empirical equation for entrainment ratio based on curve fitting of design data obtained from reputed ejector manufacturers such as Schutte-Koerting, Croll-Reynolds and Graham. Water Jet Eductors Schutte amp Koerting. It consists of a venturi located in front of a nozzle inside a column ( Ludwig, 1984 ). Transvac has a large number of experienced qualified Chemical and Mechanical Ejector specialists throughout its business that work closely Fluid Flow Design and Engineering.
