Thanks so so much both BvU and Chestermiller.
I have been wrestling with this for a while and now I think I can get my arms around the problem. I think I will need a more accurate pressure sensor as well as a very accurate thermal probe, but now I am ready to take a stab at predicting outcomes...
Hey BvU,
Thanks for the reply!
The pressure chamber is filled with water, no air. I expect that any small bubbles left in cracks would dissolve into the water relatively in the early in the pressurization process.
The pressure vessel is 1/2" thick walled stainless steel and pressure is...
I apologize for posting a question here, the prompt in the title are threw me off. I work in a small US manufacturing company. I have a BS in Computer Science and Electrical Engineering so I have just the basics when it comes to college level physics.
I hope that this is a more appropriate...
I built a pressure chamber to test small parts for leaks at 1000 psi. I can measure the pressure with an accuracy of ± 1 psi. I found that small changes in ambient temperature ± 2 °F can result in a slow but profound change in the pressure in the system, say 25 psi.
Insulating the chamber...
