...Ever heard of it? Well I have just spent the last 2 days working with these guys that do this and TBH its fookin amazing.

 

For those that dont and can be bothered to read this:

Its using high pressure water to cut away concrete among other things where pneumatic drills wont do the job. Whats impressive about it is that it runs at 2500 bar. Around 36,000 psi (their figures not mine). Now thats big presure. :) The jet that comes out of the lance leaves at a velocity over 1500 MPH. around 6800 MPS and it super heats the cold water to beyond boiling point. Twice that of the speed of sound. If they add a special gravel it can cut through 40mm of steel.

 

Sorry i'm being really boring I know, but I was very impressed :smash: :cool:

sounds really powerfull, should give to a neighbour you don like to wash his car :rofl: :rofl:

i think thy use the same idea to cut marble and granite too :)

sounds like a big water jet machine which is used like a lasor for profiling metal parts for industry.

 

amazing what will cut with enough pressure behind it!!!

So there's a sonic boom?

there is a vid of it on youtube

 

they use the same tech to precision cut, things, its even being used in surgery.

laws of physics states there will be a sonic boom , but not loud enough for us to hear due to the scale of the medium cutting through the air ....ie fine water jet....would more likely be audible as a small crack initially

Never heard of them, but that's not my reason for replying! Just had to say I'm LOVING the sig pic!! :cool:

So there's a sonic boom?

 

The strength and power of a sonic boom is governed by the size of the object that has created the boom. A jet fighter travelling at twice the speed of sound will make a less powerful boom than that of a jet airliner. As the length and strength of the noise is dependant on the length and size of the object, so a drop of water will only make a cracking noise which is what is heard when the apparatus is being used. It isn't however like a boom more like a loud continuous cracking of a whip. But it is very loud and ear defenders are mandatory items of PPE. I hope that answers your question? :)

 

 

Oh! and thanks Willy. Merry christmas
