How can I calculate the pressure drop for a vacuum system?

[Larrytsai]

Hey guys,

I am currently trying to figure out how to build a really small vacuum system and trying to maximize the suction force. I understand that in order to create the vacuum suction force we must have a pressure drop within the chamber so the molecules rush into the low pressure region. However, I am having troubles finding laws, theories, and formulations for vacuums/fans to calculate the pressure drop on google. I was wondering if you guys have any good sources I could refer to.



Thanks!
