How to calculate vacuum leakage

2007-12-21View Original

Thread Content

I have a vacuum system with about 10 cubic meters that requires a vacuum of -0.98 during operation. During the pressure test, the pressure dropped to 0.3MPa and then dropped by 0.05MPa after half an hour. I would like to ask you what the leakage is? Is this leakage big and will it have any impact on operation?
