An ejector is an fluid transportation simplified device that generate relatively low pressure utilizing the kinetic energy of pressured fluid to provoke suction of another fluid, mix the two and discharge the mixture against a counter pressure. In this study, a parameter analysis was conducted to predict the ejector performance against various operating conditions. It was revealed that the loss coefficient of the nozzle, pressure ratio, flow rate and size of suction area has the greatest effect on the efficiency of the eductor and showed efficiency of eductor is proportion to increase of flow rate.
