I was involved in a ejector design 50 years ago without the benefit any any data what so ever, it was all done from first principles, today you are lucky as there is more than enough data available at the touch of a few keyboard strokes - do some research or buy something off the shelf and model what you need from there.

It would also help if you gave a bit more detail, maybe a member has got something suitable to suit your needs.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

If you search on this site (top right corner) you can find a lot.

Based on this post I think you might be looking for something that only exists in the hands of manufacturers.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Yes, venturi pump design is done by the manufacturer. I have assumed that they developed the eductor curves were developed based on empirical observations. If you go to the manufacturer's websites, you can probably develop a spreadsheet off the published data.

Ejector selection and motive gas requirement is discussed on page 10-56 in the 7th edition of Perry Chem Engg Handbook.
