FEAR's Power- 1000psi out of a 2" opening

[assassinworks]

what i mean by hold down i know the metal will hold up but you dont have it strapped or chained that would be on the other side of the yard lol

[assassinworks]

i might be doing the math wrong or you might be if you spend as much time out in the field as i have and pipe lines blow up with 1000 + psi in them i will tell you that dont look like a 1000psi furthermore at a 1000 psi you wouldnt be able to hold it down in the set up you got thank you

@assassinworks

I'm not sure what you mean by hold it down in my set up? If you mean the combustion chamber couldn't handle 1000psi, then your are mistaken. The burst pressure of the 6" pipe is 4300 psi, and with 3/4" plate capes, I find myself to be well with in a safe operating range at a 1000psi. Seeing as the combustion chamber is not failing, I don't find your comparison applicable to whether it appears there is a 1000psi or not exiting the 2" port.

thats crap it aint even 1000 psi that compressor cant even put out that much it barely makes 150psi

@assassinworks

You clearly are not familiar with pressurized fuel/air mixes or the concept of hybrid combustion cannons. For 1mol Propane, you require 5 mols oxygen for proper combustion. The provided oxygen is in the form of compressed air. For a precharge pressure of 6.44 psi propane, approximately 140 psi of compressed air is required for proper combustion. The final combustion pressure is slightly over 1000psi and the burst disk fails at a calculated 1000psi.

@uckilljoy What do you do if the disk doesn't fail?

[uckilljoy]

@ariskk88

Vent the combustion gasses and replace the burst disk with a new one for another shot.

cool as hell man...im glad to see a real cannon...not a PVC toy...thumbs up

[18PSEHUNTER]

I swear that there were flames coming outof the barrel great vid!

[guykr10]

@18PSEHUNTER there were flames...

[HydroFred]

What the hell man. Who pissed you off? lol. Check out the HydroGun at hydrofungun.

[StopMotionMind]

I'll actually have more than 1000psi coming out of a 2" union, but the chamber is only 60 cubic inches. This will be for my hybrid.

[gdub555]

crazy!

[sooperdude1992]

is that sheet aluminum for the burst disk?

fuck thats crazy

[Gforcebond]

i bet if someone where to stand infront of that it would literally blow a hole 2 inches big through you

[drewnickel]

@Gforcebond no, it would blow a crater 2 feet big through them

[drewnickel]

@Gforcebond look at the size of the blast when it hits, that's not 2 inches, thats 2 freaking feet when it hits

[hal02modder]

sweet still of the dust cloud!

[hessy11]

crazy thats gona be supersonic

[poljaris]

i can promise you that those gases traveled at atleast mach-3

to killjoy: i love you more and more! x)
