eductor measurement

(OP)
Hi,

I would appreciate if anyone can give me any information about making an eductor, viz the measurement of the venturi, neck dia etc.

I want to make an eductor working on compressed air to clear liquids spilt.Iam expecting to make an eductor of about 5 inches length, and 10-15mm dia.

msn.

RE: eductor measurement

Please take a look to:
Pump Handbook
by Igor Karassik, William C. Krutzsch, Warren H.Fraser and Joseph P. Messina (Editors) 2nd Edition
Mc-Graw Hill Book Co.
ISBN 0-07-033302-5
Chapter 4 - Jet Pumps by Alex M.Jumpeter is amazing.
To your question, seems like Fig. 15 (page 4.18) is the answer.
Hope this helps.

RE: eductor measurement

Instead of designing your own eductor buy one off the shelf.  Schutte & Koerting has a good catalog of which I have purchased many over the years.  Don't reinvent the wheel.  Try them at 215-639-0900 or www.s-k.com

RE: eductor measurement

Eductor seems often used for liquid, and transvector, or venturi or ejector is for air or gas.  Anyway, as JeffHofacre suggests, go for off-the-shelf products, that you can find suppliers' web sites such as www.foxvalve.com, www.iprocessmart.com/itw/transvector_airjet.htm etc. Good to use a search engine, such as Google, and type the nemes you look for.
