How far can the gas be sprayed? !
Thread Content
How is the jet distance of a gas calculated? ! A small hole, 1.5 mm, compressed air is ejected from it at 7 kilograms – how far can it be sprayed? ! Thank you. . . . . . . .
What’s the purpose of calculating this? Are the conditions met? Anyway, I wouldn’t know either; just a few random thoughts: 1. Suppose it’s a tire that develops a hole and then tears apart – we don’t know how big the gap is, nor how far the material will be sprayed, but it makes quite a loud noise ； 2. Fixed volume, with no continuous gas supply; in other words, the gas is gone once it has been used up. Can it be estimated using the formula PV=nRT? 3. Fixed volume with continuous gas input, meaning the gas cannot be completely exhausted. Then treat it as a fluid!
You’re being very objective; there’s no fixed answer to such questions. I think this way: if we consider the sun as a small gas hole located in a distant part of the universe, the gas it emits can reach distant planets like Neptune, and reaching Earth would be no problem at all.
It’s the same as saying nothing; P; P; P; P
It’s becoming more and more like a filler post. Dark matter? I don’t understand it. A pressure of 7 kilograms is not considered high either; the compressed air used in grinding machines in ordinary companies is usually within 7 kilograms as well.
A hole as small as 0.7Mpa isn’t taken into account; please explain this to me, experts
This can’t be considered spamming; the original poster didn’t specify any particular conditions or environment. Think about it: Voyager 1, the first space probe launched by the United States, uses jet propulsion based on the concept of relative motion. The final stage of its propulsion system is likely to use hydrogen or helium. From its first autonomous thrust application until now, how far do you think it has traveled? It must have reached from Earth to the edge of the solar system. This distance is approximately 18 billion kilometers.
Hehe, it’s a continuous fluid. . . . .
Thank you for your participation! What I’m describing are real engineering problems related to things in Earth’s atmosphere; things outside the atmosphere seem to not require any consideration! If I asked you to think about it, you wouldn’t come to Haichuan either! Hehe, thanks for participating! ! ! !
