Seek help regarding the gas release rate from the cylinder
Thread Content
For a 10L cylinder filled with gas at 0.2MPa pressure, how long does it take for the gas to be completely released after the valve is opened (the valve pipeline has a diameter of approximately DN25)?
What do you want to do? The question you ask and the thing you need to do must be two separate things
Figure out what you really want to do, and don’t distort the issue with your own interpretation. Asking questions externally is meaningless; it doesn’t help in solving problems. “Finish putting it away”? How should it be defined? Is it considered that the gas has been released when the pressure inside the cylinder is equal to the external pressure, or only when all the gas molecules in the cylinder have exited? The diameter of 25 mm is useless in this case; the diameter of the bottle valve is 4 mm, and different opening degrees of the bottle valve result in air flow speeds that differ by many times. If it’s turned on fully, it’s over in a few seconds – is that the answer you wanted?
