Is it possible to create a vacuum from a non airtight seal?

Question

wouldnt a vacuum still be created, the vacuum is from venturi and is connected almost right next to the portion I need the vacuum to suck from, but its not airtight. I figured it would still work, just not as well as it could. Any help, suggections, advice, etc. Thanks.

Answer 1

As long as you're pumping out more air than is getting in it would cause lower air pressure inside which would be considered a vacuum.

Answer 2

The definition of vaccume is no air at all, so no, you cannot crate a vauume from a non air-tight.

If you are talking about a vaccume cleaner (sweeper) then you need to have it repaired at a shop.
