How far can 8kgf of compressed air be blown? !
Thread Content
Make a small hole of 8mm. How far can compressed air at 8 kilograms be sprayed? Is this a gas jet?
Theoretically, it can be reached even by diffusion over greater distances; what do you consider to be the boundary between reaching it and not reaching it? Time, concentration, or what?
It’s best not to conduct such experiments. If you carry out pressure tests on pipes in a factory, you’ll understand this well. It is said that gas at 0.4 MPag, when ejected from weld holes, can penetrate the human body; you can imagine just how high the pressure must be.
Is it that exaggerated? It’s only a few kilograms!
It’s not measured in kilograms; it’s the pressure that matters. Water is ejected from an 8MM hole, following the same principle as a high-pressure water gun
Solids are the scary ones; gases are immediately neutralized by normal pressure as soon as they emerge
The energy carried by the gas is still quite large.
Related to temperature and air flow rate. At room temperature, when less than 300 Nm3 of air is released into the atmosphere through an 8 mm aperture, the instantaneous exit flow velocity exceeds the speed of sound (300 m/s). However, its speed decays rapidly in the air.
The sound can be a bit harsh, and it’s possible to sense the wind at a distance of about 3-4 meters. If one is too close to the outlet, the wind can blow through one’s clothes; it’s best not to conduct such experiments as they are dangerous. When the pipes are thin, this may cause them to vibrate violently and even break
