Do You Know The Difference Between...?

Supersonic fluid dynamics is pretty interesting.
I still dont fully understand it.

[RiehlScience]

Could you explain more about the speed of sound in rocket nozzles? I’m intrigued by the physics of nozzles and things like Mach diamonds.

Tilting the shot was a nice touch! Good work 🍷

[reggiep]

Are the Portuguese police not watching you closer these days? Or have you told them of you endless rocket projects?

Either way, bro.. You're getting there and to see massive grins on your face makes me happy.

Enjoy life.

Yesterday i was basically trying to make a woosh rocket with an extremely small nozzle and it blew up and i lost hearing for an hour

Integza just needs a bottle to make a rocket 😂🤣

[AJBD]

A rocket is something you make as bomb-like as possible without going boom. Vroom and boom. Very similar.

[PsRohrbaugh]

You know what's the difference between a bomb and a rocket? Whether the FBI wants to know your location.

[mineyoucraftube]

same for.... batteries! all 3's goal is to store a large amount of energy and to be able to use it very quickly (for batteries it's at least the case for lithium ion(lithium ion rocket maybe?)) that's why they all blow up
and also why we can't make a safe powerful lithium battery, we're litterally trying to make a working bomb that doesn't blow up
(i know it's unrelated to the video, but i had to get it out of my system and that was a perfect bait at the start)

Make a screw on nozzle for a whoosh bottle

[MagruderSpoots]

Higher pressure is what matters. Smaller nozzle equals higher speed but also higher pressure. PSI times the effective nozzle area gives you the approximate thrust.

[SilntObsvr]

And rather a while ago, it was found that if you *can* get your exhaust to the speed of sound with a convergent nozzle, you can then let the gasses *expand* in a divergent nozzle and get even more exhaust velocity. The SpaceX Raptor III engine has an exhaust velocity of about 3.8 km per second -- but still just Mach 1 at the throat.

[죽은_시민의_사회]

When I was a kid I would make nozzles with paper clay. It didn't melt, but it was very hard to keep the nozzle attached to the body.

[Popstylez]

Great illustration. Especially for dummies like me who need pictures lol

[CUBETechie]

After you have access to an SLS printer you need recreate this rocket but slightly bigger 😊

[leight]

thats not a shockwave g, just condensation

[Techy_Fellow]

Pls make tesla turbine powered car(use liquid nitrogen gas or oxygen). Btw very nice vid

[impyre]

The speed of sound is essentially the speed at which physical interactions can be transferred from one air molecule to the next. This is the speed at which physical shock waves can travel through the air. Increasing the pressure does not increase this limiting velocity. When the speed of gasses leaving the rocket must be higher than the speed of sound for gases at those temperatures and pressures... then you no longer have a rocket and in fact have a boom... Since the reaction will cause the pressure to increase in the combustion chamber faster than the exhaust can escape.

the end feels more like you’re talking about a siphon effect as well ngl. they reach the speeds, but them shooting out due to high pressure suddenly causing less molecules in the area, thus low pressure and sucking the rest in? at least that’s another way i was seeing this. someone help me understand pls

[rbnotacus]

So when you're designing a Nozzle, how do you measure the exit speed?
