Thankyou so much, it was an excellent explanation and I got to know new things like hypersonic, also my other concepts got cleared. You are a wonderful teacher😄
It will be easier to break the sound barrier at higher elevations since the temperature is low, thus air viscosity is low, resulting in a low density of air where less air molecules can compress on the aircraft body and in front of it. Making it easy for the aircraft to break the sound barrier at high elevations. Sorry I am not living in the US, because of that I can tell which state weather condition will result in optimism acceleration of the aircraft to the speed of sound, thank you.
I believe it is the opposite! In fact, the air at altitude is denser than below and there are no fewer molecules. This is a nonsense that was introduced at school, without any coherence with the true science of facts. Because we breathe with difficulty at altitudes, it is convenient to say that there is less air! This is not correct, because what actually happens is that we breathe air with lower pressure and our lungs are unable to absorb this external air, due to the lungs being conditioned to work with air at 1 ATM of internal pressure... The air The external surface has lower pressure due to the much more intense cold, which makes the molecules lose their kinetic energy and thus, atmospheric pressure is lost. Therefore, sound at altitude propagates more slowly, due to the cold air being denser. Sound in a denser gaseous medium loses speed compared to a less dense medium, as occurs with the air below the atmosphere (hotter). The denser, colder air; it loses viscosity, increases compressibility and its elasticity is also much lower! Therefore, sound at altitude is slower and takes longer to gain pressure due to less elasticity. All of this combined makes air at altitude much less efficient in transmitting work than warmer air lower in the atmosphere. Warmer air, less dense, more kinetically energized, therefore, increases the speed of sound. I hope to have given another point of analysis, more congruent with the facts of the physics/chemistry of air at altitude.
I think Colorado would be easier because the temprature in colorado is 0 celcius today . That means speed of sound will be lower so we will need less speed to go for mach 1. But on the other hand Texas is 25 celcius today so; speed of sound will be higher ,that means we will need more speet (to be exact 1.04478471063424 times more speed)
The air is thinner in Colorado my dude. To but it into basic terms, Colorado has mountains, and the location and elevation makes it so the object travels more distance in less time. Texas has more humid air, this making it slightly slower to fly.
Great question! Of course! Mach number just tells us how much faster something is than the speed of sound. So, this speed is not relative. If the object's speed in the water is equal to 100m/s, then you would still divide it by 340m/s to get Mach number. It doesn't matter where the object is.
where would it be easiest to break the sound barrier ... at 50,000 feet .. its colder than colorado and texas on the first of march ... except this year as I recall texas had snow porblems around then ;) ... while Colorado was flooding ... but usually Colorado ... even easier at Alert in Canada ... its even colder ...
Thank you! In my opinion, the earth is flat and it matters - and one reason is: I DON'T believe we are screaming through "space" right now WAY faster than the speed of sound.
@@AliyaBurkit Thanks for replying. I guess my question would be: but does that make any sense? Also, in addition to what you said, we are ALSO supposed to be (I call it) screaming through space along with the sun at an even faster speed than that!
@@AliyaBurkit ...But I REALLY appreciated your concise explanation of the speed of sound! Way to go! By the way, did you know you can count to 31 on one hand, 1023 on two, and as far beyond that as you want? That is one of my specialties, which I called "binary dactylonomy".
I would come to class everyday if she was my professor and would not mind failing the subject over and over again only if she would be the one to teach it 😂😅😍
One thing that bugs me is that Ernst Mach wasnt Austrian at all.. We was born in Austrain Empire yes but in today Czech republic and was born into Czech-German family (half Czech half German) So not totally Austrian.. Othervise great video :)
Too bad lighting strikes go beyond Wikipedia's Mach speed chart which would be ultra hypersonic speed. Faster than a bullet, but one-third the speed of light. If spacecraft can travel as fast as lightning, then we will hit Mars in no time.
I will listen to anything she has to say and defend it with my life!!
haha ikr. what an absolute babe eh?
Awesome lecture.. Loved it ❤️ especially when Freddy mercury showed up lol
Glad you enjoyed it!
In Colorado it would be easier to break the sound barrier because at higher altitude the saturation temperature is less.

Damn beauty with brain 😍😍😍 , wish I could have professor or teacher like you, might have full attendance😅😅😅 and clear about the topics 😊
To your question- it would be easier to break the sound barrier at low temperatures. Subsonic speed lower energy.
Well explained Madam. Very easy to understand forTks persons of my age (70 years). Tks for sharing. My best wishes to you.
You are most welcome
@Aliya Burkit Thanks for the video , that was very helpful for me , well Huge gratitude from India 🙏🙏🙏🙏
Glad it was helpful!
Cleared all my doubts in one simple video!!
You explained way better than what I learned in my 6 months of ground classes ☺
God bless!!
Thank you so much! Good luck with your classes!
@@AliyaBurkit Thanks ma'am
Hey there ! Great content ! I wish I found your channel earlier. Thanks for sharing the knowledge :)
Beautiful lecture as much as like you.😊

Wow.. Explanation is as clear as you. Thanks for this.I have learnt much knowledge even from small video and btw you are cute.
Glad it helped!
@@AliyaBurkit thanks for your response Aliya. Your concepts surely help me in my Masters in aerospace. Stay safe and healthy.

I'm so glad!
Speed of sound is lesser than the speed i fell for your teachings 🫠
Good explanation 👍🏼
Thank you!
please keep posting videos, you tech very sweetly,, please
Great video this is the best

Hello, may I ask, are we are able to calculate Mach number if the medium is water?
Great question! Of course! Mach number just tells us how much faster something is than the speed of sound. So, this speed is not relative. If the object's speed in the water is equal to 100m/s, then you would still divide it by 340m/s to get Mach number. It doesn't matter where the object is.

interesting lecture but you forgot to mention that the temperature should be in Kelvin for a simple calculation and better result
True, thanks for pointing that out!
Can you please explain the one that uses 661kts
thank you

Hypersonic ... is that the same as Transonic .. or is Transonic even higher up

For the temperature is it in kelvin or Celsius because I had a question like this in my test but temperature was in celcius
looking at the units she is using, it's 'k' so kelvin
Convert to Kelvin by adding 273
Thank you! In my opinion, the earth is flat and it matters - and one reason is: I DON'T believe we are screaming through "space" right now WAY faster than the speed of sound.
We are going around the Sun at 30,000 m/s, sp yes, much faster than the speed of sound

Are You working in NASA mam?
why you take dry air? air may be dry or wet so the wet air will be 16 why not take?????????????
Just for cleanness of calculation for standard. It doesn't have to be dry in regular problems.
its 8.31 or 8.13?
8.31
8.31. Should the unit be in kJ/mol.K?
