Hello,
I am new to this forum but I have a question for you all. It is about the pressure in a system that changes when leakage changes. The test setup has to following components:
- Air supply with 8-10 bar
- Pressure valve that can be manually adjusted
- A flow meter that measures the pressure and the air flow
- A test object with a valve that leaks air
When testing the the manually adjustable pressure regulator is set in such a way that the test object is subjected to 2000 mbar absolute (1000 mbar overpressure). At this pressure the valve always has some leak rate, let's say 10 L/min. If I try to close the valve further with my hands by applying pressure to it so I decrease the leak rate, the pressure before the valve should increase. This is also registered by the flowmeter.
However I would like to know if there is a theoretical way to calculate this pressure rise.
Can anybody give me some advice as to how to tackle this issue?
I know I probably did not give you all the info but I like to learn the approach and than start talking numbers
Hope to hear from one of you.
Regards,
Max de Jong
