I was wondering if there is a base line number/average for vacuum I can use to help calculate the size and amount of vacuum cups one would need.

I know it depends on leakage, distance, # of cups, psi applied etc. but I was hoping there is some sort of baseline I can use as a starting point.  I'm trying to make a force calculator with excel or maybe there is already one on the internet.

With 87 psi how much vacuum (inHg) could I pull.

Thanks for any help....

You need to hunt around and find the "air eductor" or "venturi" you are going to use to create a vacuum from "87 psi".

Example:

Then it's just the surface area verse the vacuum pressure that gives the cup's lifting ability.
