Liquid Jet Ejector Nozzle Design

Use the ejector manufacturer's performance data. The information should be at least tabulated in their technical data sheets.

Guru, I am the original poster.

Indeed,while referring/analysing two different vendor data this question arises.For the similar specification, which is :

suction fluid (water) flow = 10 m3/hr,suction fluid pressure=Atmospheric,Temp= Ambient,Available motive fluid(water) @ 11.4 kgf/cm2,Driving liquid pipe=50 mm-NB.,suction fluid pipe = 50mm-NB.

One Vendor is asking for 10 m3/hr motive fluid, while another one is asking for 14 m3/hr.This question is more worthy in terms of academic interest rather than 4 m3/hr motive fluid requirement difference because of may be abundance of availability.

I just wanted to understand basic engineering for designing liquid jet ejector. If required nozzle dia. of 25.4mm may be consider for calculation purpose.
