Dope Tech Episode 2

<<@ArturoMorala-o1j says : Good nice learning>> <<@3dgar7eandro says : Epic 😎👏🤩👌>> <<@El-Meffy says : Wouldnt that mean 30% more air to "push" off essentially as less air would be less windy to a degree right? If ya get what im trying to say.? Also boeing 777s ect flying that slow at the landing stage with all that weight at that slower speed doesnt compute in my mind how isnt it dropping like 500 bricks>> <<@Britanyali says : I believe there is a trade of between efficiency due to density and air molecules sucked at that high levels to generate thrust..because nature is giving you while taking it away>> <<@misterxyz5958 says : Besides no bird up there to enter the engine and cause fatal evident I think😂>> <<@ikobyzev says : Where is the rest of the video?>> <<@samadarshimaity1143 says : But doesn't it also make them travel more due to earth's curvature? But probably the reduction in thrust offset this overhead... I guess.>> <<@awaan05 says : Bird: sometimes I can see a plane infront of myself>> <<@chocolate-co9iy says : the guy who made planes is SUPER smart>> <<@Mr_steak_everyday says : Most electricity at this height. Commercial Jets don’t use Jet fuel once they are over 25,000 feet.>> <<@Hari_naam_rasik369 says : ❤️>> <<@darksoulwarrior9662 says : imagine the speed of the ISS up there.. Jesus>> <<@enteradj says : So it isn’t about money then>> <<@SUB2NARROWW says : Oop oop pull up>> <<@jakebishop6043 says : For reference Everest is 28k close to 29k feet>> <<@williamdiaz7965 says : Planes fly higher cause thin air means less friction means less fuel spent. WAY LESS DRAG WAY MORE SPEED for the same amount of fuel per seat mile.>> <<@SeanLangford-z7u says : ALL LIES AND I'M WAYYYYYY TOO SMART TO BELIEVE AND FALL INTO ANY OF THIS BULL CRAP!>> <<@N0Xa880iUL says : Holy loop!>> <<@fortezzasolutions says : It seems this is fairly common knowledge. With that being said I do like the visuals and breakdown.>> <<@DeEmperor1 says : I knew this since secondary school when I wondered why not fly close to ground in case of emergency that requires fast landing.>> <<@RAYTHEBULL says : Air is thinner so less drag. 6 words got the point across, didn't need a long ass video>> <<@dichtungundwahrheit says : Pero si la atmósfera es menos densa, ¿la sustentación no es menor?>> <<@fhhgggh-k5l says : 😂😢😮>> <<@lpls says : Now for homework: why don't planes fly even higher?>> <<@cantDeportMe says : What is the relation from turbo efficiency to air density>> <<@ylihao says : So he says that jet engines work by compressing air at the intake, mixing it with fuel and igniting it and so on, but doesn’t explain how is this more efficient with less air 🤷🏻‍♂️>> <<@MANOJ_PMHH says : The Reason Why Plane Fly Is Less Noise And At Trains More Noisy.>> <<@maulekuul says : All the Socialists in the replies demanding companies do things the more expensive way.>> <<@Porkeats says : They're trying to keep everyone grounded now anyway to compartmentalize the news.>> <<@tasmanianduval1931 says : But somehow less efficient with internal combustion engines... Less dense air means you're having more trouble ignoring the fuel which means you're burning less efficiently than you could. Like he said, it's more about money right?>> <<@Gimmickvr says : Honestly, that actually sounds like a win-win for both the airplane company and the people riding the plane because they get to the destination faster and the company pays less money>> <<@sejengkalsehasta3211 says : And you need natural rubber to make the plane tyres...at 10 km up the temp of the tyre is - 50°c and when landing the temp is +550°c>> <<@nck7269 says : Logical>> <<@camdenashby8170 says : Man satisfactory modeler would have saved you hours on hours lol>> <<@DianL5517 says : Its a win win solutions then, after reading some comments>> <<@rickydawn4431 says : Not sure the ‘since you’re in the air less you burn less fuel’ sentiment really makes sense considering there’s aircraft that will get you to a destination much quicker (be in the air less) and burn way more fuel.>> <<@brawlstars895 says : When the plane is high it takes more time.>> <<@kylaharris2296 says : imagine what the pilots have to go through going that high constantly>> <<@NintenDub says : But you fly further higher>> <<@igelbofh says : There is also a lot less air to provide lift, so you have to run your engines faster. So it is not at all that efficient. Also, the gasses of the jet engines primary turn the engine itself which in turn turns the fan disk in front, it's not the gasses that move the plane, it's the outside air that the fan disk moves. The higher you go the more RPM you need for same volume of air. Planes actually lose speed for the same RPM setting the higher you are.>> <<@AnthonySomes says : Why not go to 50,000? Or higher>> <<@Karma-The_Eagle_philosophy says : But don't they also get 73% less molecules to push so, resulting in less thrust?>> <<@d.n.3652 says : There’s also the benefit of avoiding terrain>> <<@riyaansheikh7470 says : Why not go even higher?>> <<@natesnews5105 says : I has been summoned>> <<@marcd1981 says : The engine animation was very well done. Now I'm hoping this channel has a video for an engine!>> <<@brianhyde8017 says : Why 30k feet and not 40k feet. What restrictions cause that upper bound? If the efficiency is the same the. You travel farther at 40k feet, but I wonder how much the efficiency changes at that point.>> <<@reinermensch..369 says : Doubt:Then why they dont fly it higher as there will be more less feul wastage and we will be at our destination faster>> <<@divit67 says : Also to avoid birdstrike, large buildings, and civillian disturbances>> <<@LGNDxFPV says : Lol I love how "The point is money, and here's the science behind how they can take advantage of this second">>
