I have a question about vacuum pres
(OP)
I have a question about vacuum pressure differential ...so I have a pipe connected to a chamber with a thin beryllium window separating them and on the pipe side the vacuum is 1x10 - 4 torr and on the chamber the vacuum is 1x10 -7 torr . So I would calculate there is a difference of 1x10 -3 torr . If this is correct then how much force is pushing on that window if that window surface is 1" x 0.5" rectangle?
Thanks

RE: I have a question about vacuum pres
Why don't you say what you think and then ask if its correct.
Hint - work in consistent units then force = pressure x area is a good start point

Also: If you get a response it's polite to respond to it.
RE: I have a question about vacuum pres
Its a pressure difference, so its 1 x10-4 - 1 x 10-7. pretty damn close to 1 x 10-4....
Think of it the other way around. If you had one side at 1 x 10^4 (10,000) one side and 1 x 10^7 (10,000,000)the other, the difference wouldn't be 1000 would it??

1x10-6 pounds
using the correct pressure differential.

This is NOT consistent with your pressure values.
