B Maximizing venturi vacuum pump

  1. Apr 1, 2017 #1
    I have a venturi gas vacuum pump on the the end of an exhaust as an example. The exhaust spills out at 2.5cfm and 2 lbs. On a average of venturi efficiency, how much cfm at what pressure (or ratio alike) would be needed to eject the exhaust gas to near vacuem?
    As a secondary question, what would evacuate the exhaust faster, a high pressure low cfm input, or a low pressure high cfm input?
    As a third question (sorry for so many), how would the venturi effect the sound as the exaust is lowered in temperature and pressure and then gained in pressure?

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.
