I feel like we may be describing the same thing, but now I want to make extra sure. Lets try this
EXAMPLE 1
-Initial conditions-
Pressure P0,
Total Volume V0,
Water volume W0=0.9V0,
Air volume A0=0.1V0.
System is sealed
Assume air is not diffused into water, and is a distinct pocket above...
Thanks LittleInch
To clarify what you're describing as 10% of the air volume diffused in water:
eg 10m3 total volume
At some point during the test after the system is sealed,
9m3 is water
1m3 is air, fully diffused through the water
This could make the water volume appear to be 10m3, but...
Cheers, that looks good. Creep is exactly what I was thinking, yet somehow I managed to use this simple keyword in a search and missed the rich vein of information on exactly this topic.
Diffusion makes a lot of sense too when I think about it. But what effect would water and air diffusion have...
Hi everyone,
This is about water pipes, but in a sealed system so I think pressure vessel mechanics may be more applicable.
I have been testing PEX (polyethylene) water pipes by assembling short lengths with a gauge at one end, and pumping water in through the other. When filled and pressurised...
