Calculation of inflation time for vacuum equipment
Thread Content
There is a device with a volume of 10 m3. The pressure inside the container before pressurization is 5 kPa gauge. Compressed nitrogen at 5 barg is used to pressurize the device; pipelines and valves are not considered for now. It is necessary to reach a final container pressure of 3 barg. How much time will it take, and what will be the amount of nitrogen consumed?
Without the temperature, it’s hard to calculate. Furthermore, the duration of pressurization is related to the size of the piping, the Cv value of the valves, as well as the length of the piping and the presence of elbows, etc.
