Right?! I was at one of their concerts here in Houston in 2008 at the Toyota center. Lars was mentioning how they hadn't been to Houston in a really long time and that we wouldn't be disappointed. To this day, that was the loudest concert that stadium has had. Toyota center placed a decibel limit for all future concerts after Metallica performed because towards the end, it started raining nuts, bolts, and screws on the crowd and stage from all of the rigging above! I remember headbanging along and a bolt about the size of my pinky hit me in the back of the head. I thought someone behind me hit me until I started seeing people covering their heads with their hands. I believe this is why Metallica prefers to have outdoor performances or at least a bigger venue. You could say they made it rain metal.
After the Rocket clears the Tower and is accelerating at full power, the 'sound pressure waves' of the different Rocket engine types blend together into a very unique sound. Even if you are 5 miles away, the sound is enormous. As Rocket gains altitude, there is no sound suppression system and you hear it full volume. Even when the Rocket is 25 miles up, you can still hear the engines.

Saw Metallica in 19 and 92. Like yours, it was the loudest show I have ever heard. The first three songs were impossible to understand, my ears could not adjust.
For anyone mad that the water is wasted, I would like to remind people about the phenomenon known as the water cycle it is impossible to waste water, this water will eventually evaporate and fall back as rain thus refilling the water table this is how it has worked for billions of years and will continue for a lot more. (If we stop climate change, if not the water cycle will get dusrupted due to the increased frequency of droughts) we are using the same water that the first lifeforms on Earth used. The only reason your taught to not use too much water is so you don't use water faster than the reservoirs can fill up. This is why (in the U.S) during a drought they advise against using too much water and avoid using water to wash your car as the lack of rain means that the reservoirs can dry up the water isn't gone by any means once the drought ends the reservoirs will fill up again.
The ultimate proof that Rocket launches needs to be re-evaluated. Just imagine 1 5 0 747 planes taking off at the same time using full power. This is the equivalent of one large Rocket going to space. Imagine what kind of Space Plane we could build. It could bring 10 times more resources to space and cost 100 times less than today's expenses. Looking forward to improved Space aeronautics for future generations.
It does through a solid body of water, but a crucial aspect of these water deluge systems is that they produce billions of small water droplets which all absorb and redirect the energy. The spiral nozzles and direction and strength of each stream of water is designed to maximise the creation of droplets rather than just engulf the whole area with a solid wall of water.
@@ImapatriotUSA ... Technically you are of course correct ... but you miss the point entirely (and not all rockers use the same fuels BTW). The video is about water emitting sound suppression systems built into the launch pad ... NOT the contents of the rocket engines exhaust (which does nothing to suppress sound) ... these are two (2) completely different things. Because of this the title of the video is incorrect.
It said MOST of the steam involved is from the condensing rocket exhaust (which is almost all steam). Some is from the deluge water boiled off by the heat of that exhaust. They did not explain, but I suspect the damage that is prevented, is from the acoustic energy that would otherwise reflect back up into the launch vehicle. The deluge must be turbulent, to disrupt & absorb that acoustic energy before it gets reflected. If (as suggested above) the wasted downward directed energies (kinetic & acoustic) were directed into some kind of storage system with low impedance, perhaps it would serve both to abate reflected acoustic damage, and salvage some of that wasted energy. Whether that is a practical idea, requires some technical and economic calculations.
@@blazingguyop yes, true, but it's two different levels of exposure. Then how much cost savings you have by using salt water? And how much over dimensioning you have to put? Is it cost effective? Intelligent to do? I don't think so. You never start a trip with already a bad leg
You missed a third source of water. The liquid hydrogen and liquid oxygen become water as they are combined in the combustion process to launch the rocket. Come on now!
This whole video is doing a disservice to those who watch. You left out the water source and the launch locations and the abundance of fresh and salt water in the area where the launchs happen. Many of the rocket facilities are in the south where there is plenty of fresh and ocean water to dump into these platforms, so no people its not your drinking water getting wasted. It's not your farmland water getting evaporated. Chill
You shouldn't burn in the subtitles, so large. Remember, some eccentric lunatics, like me, still watch videos on a proper screen rather than a mobile phone. Mobile first is great, in theory, but the world has forgotten that not all web browsing is done on a mobile device.
Why is this so USA limited? The Soviet developed R7 family of spacecraft do not seem to need water, except for protecting the concrete beneath the burners. Also the Chinese. Everything the USA does seems crude.
Without extra information on the units, this is an amplitude graph. If the Y axis is in decibels it's an amplitude graph, if its in units of distance it's a velocity graph. Wave velocity changes depending on amplitude, frequency and phase position, with peak velocity occurring at zero crossings. Since the speed of sound is constant, both amplitude and frequency are required to calculate wave velocity. Wave velocity is inherently proportional to amplitude and frequency (∆Ydecibels/∆Xseconds = Velocity/second).
@@you2tooyou2too So looking at it again, I can put it more simply. Its not one of the other - both amplitude and velocity are two values shown on the same chart. Amplitude is the Y axis, and velocity is derived from the properties of the chart. Amplitude is the maximum and minimum value at the peaks and troughs. Velocity is represented by the slope at any given point. The velocity is the rate of change from peak to trough represents the particle velocity, its how rapidly the displacement occurs (or rather the energy behind it, because its also not frequency). With a square wave the change is instant, and the particle velocity is very high as the wave instantly changes 'polarity' for lack of a better word. Sure, the velocity is also changing in a sine pattern, but its a derived property from the graph we're looking at - its not wrong theyre two different properties and sine waves exist in all sorts of different systems.
So, a year later, my friends in Phoenix, with their swimming pools, still have water coming out of their faucets. And I'm sure you've heard about the massive snowpack melting off and raising the lakes out there? Bunch of nervous nellies 🙄
Not at all, the water isn't wasted, this is Florida, all you have to do is dig a small hole and within minutes you have a pond. It's brackish swamp/sea water that sits in the huge ponds at the launch complex, and after getting pumped to the pad it drains right back into those ponds. The "environmental impact" of the deluge system is zero.
What’s up with the shit title? The rocket is not ejecting the water. The water suppression system is ejecting the water for the rocket. The water suppression systems start prior to engine start. For example on the space shuttle launches the water system would start flowing for something like 4-6 seconds prior to engine start.
by electronic device do you mean the ones in the rocket I'm sure there are also protection for those maybe there's a layer of protection that can dissolve vibrations .u mention sound waves travel more faster in fluid,what happen to the sound waves that travel in water when it got evaporated and as we know water can flow in a direction given it's shape Don't you think they also meant in a way if sound waves travel more faster in a fluid that air then they could use the water as a medium n give the direction where the sound waves would go and not damage the electronic ?
They should take that extra takeoff power and have it turn a Tesla turbine to generate his/ Elon's battery Banks. Waste not. Or the energy could be stored in massive flywheels. It's easier to keep a mass moving, once it's moving. One only has to build on it from there....
It would be interesting to see how effective a 'waste energy' recapture system could be. Perhaps a huge 'windmill' or turbine below the launch vehicle (rather than or in addition to the deluge system, could drive a compressor or (yes) kinetic storage device for other purposes.
Half a million? Is that all? The Oil drilling related Fracking Service companies use 24X's that much on a directional oil well. EACH!! Yeap, taking 12million gals of usable water and turning it too waste!
