In: Misr Journal of Agricultural Engineering 2012.v.29(3)Summary: 17ie aim of this research is to evaluate hydraulic performance of prevailing chemical injection equipment used with pressurized irrigation systems including; (I) By-pass pressure differential tank. (2) With suction pi,oe of irrigation pump, (3) Separate electric centrifugal pump, and (4) Venturi, to help in selecting an appropriate chemical injector according to field and operating conditions. The main results in this study can be summarized in the following: *The average of injection rates were: 190, 380, 1000, and 1175 for venturi, by-pass differential tank, with suction pipe of irrigation pump, and separate electric centrifUgal pump respectively, at pressure drop or in·igation pressure of 100 kPa.
