The discussion revolves around the concept of vacuum pressure and its potential to be multiplied, drawing parallels to hydraulic systems where pressure can be amplified. Participants are exploring the implications of creating a vacuum in a hydraulic setup and questioning the nature of vacuum pressure compared to fluid pressure.
The discussion includes various perspectives on the nature of vacuum pressure, with some participants expressing skepticism about the possibility of multiplying vacuum pressure. There is an ongoing exploration of the limits and definitions surrounding vacuum and pressure.
Participants are considering the constraints of vacuum pressure, noting that it is fundamentally different from fluid pressure due to its nature as the absence of pressure, which raises questions about the maximum achievable vacuum pressure.
Perhaps you could explain the configuration you have in mind. If you pull on a hydraulic cylinder, you will push fluid out in front and draw hydraulic fluid in on the back side.Idea04 said:Homework Statement
I know with hydraulic multiplication a small piston can create an increased force upward on a large piston. But if you take the small piston and pull upward on it creating a vacuum. Would the large piston have a multiplied vacuum force pulling it downward.
No. Vacuum is the absence of pressure. There is a pressure limit for a vaccum: zero. So the greatest net pressure you can create by creating a vacuum is the ambient pressure.Idea04 said:I'm wondering if vacuum pressure can be multiplied in the same way fluid pressure can be multiplied.
