Abstract

The aim of this experimental is to investigate the efficiency water ejector. The effect of nozzle position on its efficiency was investigated. Nozzle position varied the ratio of nozzle-to-throat spacing to throat diameter (X = L/D) with values of 0, 0.5, 1, 2 and 3 respectively. The maximum water ejector efficiency obtains for nozzle-to-throat spacing to throat diameter ratio is approximate 14 %. The experimental results were found in good agreement with the ESDU design guide.
