Calculation of the leakage rate in vacuum systems
Thread Content
The interior of the device is under vacuum conditions, while the outside is at normal pressure; this inevitably leads to air seeping into the system. How should the amount of air that leaks in be determined?
It depends on how large the specific pressure difference is, as well as the size of the specific suspected leakage points
The outside of the container is at atmospheric pressure, while the pressure inside is 12 kPa (gauge pressure). The container is cylindrical, with a diameter of 5m and a length of 60m.
