Please open a school bro I'll join my child in you're school... I'm in final year civil ENGG. I'm still learning my syllabus on online... Because not even a single staff having a practical knowledge about my field....Let my child learn science in a better way.... Please consider about opening a school and if you need any financial help may me and my friends will help you... Kindly consider I'm trying to say this from your first video but....
Now it's the time....
Do consider...
Thank you...
Nice idea wow
Indha mindset ah change pannunga bro.
It's all upto us.
But we simply blame others ( like a teachers don't have enough knowledge or practical knowledge to teach us) without even any hesitation.

hai Anne, im from Malaysia, i duin my final bac mech eng, i neva miss ur single video, every time u presented new stuff i digest it very well, i want more physics related video, such lens law, Archimedes priciple, machinery's physics and so on.
Hi bro I am medical aspirant and preparing for Neet I saw many of your videos it was really good and I understand many of the Physics topics clearly in CZcams many people teach physics but it does not your video for Tamilnadu people if you teach physics in Tamil very useful and I will suggest you to start physics classes in Tamil for Neet and other competitive examinations
Thank you ji.. oru small doubt.. this technique used only for cryogenic system.. but in solid propellent what type of cooling system can be used? Can u describe??
எங்கள் மனதில் இருக்கும் சந்தேகங்கள் எப்படி உங்களுக்கு தெரிகிறது.... தொடரட்டும் உங்கள் நற்பணி.....
Dear host,
I appreciate your work. There is a small concern though. In the video when you are talking about how hot the nozzle gets you are talking about the temperature, not heat. Heat (unit joules) and temperature (unit degree centigrade ) are two different measurements.
This is a common misconception. Another example is many people still thinks that the unit of the weight is kilograms. They lack the basic understanding of what is mass and what is weight or in this case, what is heat and what is temperature.
My intention is that a good educational video channel such as LMES should be free from such misconceptions. I think your channel with a subscriber strength of 8.5 Lakhs has responsibility for this.
Consider this comment as a constructive note.
கற்க கசடற..!
I dont get you... They talk about why doesn't the nozzle melt... Melting is basically based on the material's melting point which is measured in temperature having a unit of celsius... From where heart came into...i mean yeah heat has a role in it...but the subject of concern is why doesnt the nozzle melt..
Navin,
You are saying you didn't understand my comment, but you haven't asked any question. What exactly you did not get?
Let me put in different words.. In the video when the host said " ..rocket lam lift aagum pothu 3200 degree ku mela heat produce aagum..." My objection was 3200 degree is not heat. It's temperature. He continued to use the word 'heat' to denote temperature in multiple occasions. "...ivlo heat la kuda nozzle melt aagathu.." etc.. So I thought maybe the host is misconceived.
@@ELAMPARITHYMOORTHY since u r more educated, plz make similar videos.

Face mask and safety gears podunga bro while showing experiments.. Appo thn.. Childrens ku.. Lab safety pathi therium...
Superba
Safety is no.1 priority
1. As u said the heat will not be that much high in the nozzle. Bcoz the nozzle will evacuate the fuel at the same time nozzle reduces its temperature and when it goes in one place to another within air boundary it automatically reduces its temperature as u previously explained in cooling of two wheeler engine.
2. Above the air boundary there is no medium to transfer nozzle end heat to nozzle.
3.if u want to check whether I said right or wrong u just see the gas torch. It will not melt though it is in bronze but it can melt the metal. Whereas if u go to the metal very close,then the heat will reflect on the nozzle and it will try to melt the nozzle.
These same technology was used in Kerosene stove also...

LMES brothers pls clear my doubt....
Without oxygen there is no fire...
Even in our space there is no oxygen..
Then how rocket fuels are burning space... Or Niel Armstrong went to moon without using any type of fuel...
Iam had this doubt in my school days, now I completed my degree.. I asked many of my teachers but no one gave me a proper answer. Still this question follows me pls make this as another video...... Pls
Humble request from ur student
@Vijai Kumar They use Cryogenic fuel to burn in space. Liq. H2 as fuel and Liq. O2 as an oxidizer. They're used in the upper stages of any rocket engines. Solid propellant and liquid propellants are quite commonly used during lift-off and stage separations.

After long time....! A good video from LMES...✌😊
Liquid hydrogen is naturally cool ....!?😐
Hydrogen is a gas only after you cool to less than minus 253 degree only it will become liquid so that we can store more hydrogen in less space
LMES make each & every vid are good only😊 bro
Simple and clear video.
If they use only solid propolent fuel how to reduce exhaust temperature
Amazing question
@@amirabbas4720 👍
SRM ( SOLID ROCKET MOTORS) mostly uses ablative type nozzle which means the surface of the material will be vaporized by the heat and that vaporized gas will create a thin layer between the nozzel wall and hot exhaust gases this gas will absorb heat and protects the nozzel from melting
@WRANGLER FC SRM will also work in space there is no problem in it do u know third stage of pslv is also solid rocket motor and even
Delta-4 rocket used a solid upper stage for achieving required dv( difference in velocity) for sending Parker solar probe in heliocentric orbit
@@Nammaooruscience nice 👍
Romba naal doubt innaiku than clear aachi bro....
Thank you🙏....🚀
I got a small doubt bro. When the liquid fuel absorbs the heat of the exhaust , it loses its temperature i.e the temperature increases, so when temperature increases it will expand , how they rectify the expansion issues. Please explain.
Thanks in advance
vijaya kumar k rocket engines have turbo engines to control the gas flow before combustion. Actually expanded gases helps the turbo pumps to throttle the fuel outflow which in-turn helps to achieve higher thrust. Checkout everday astronaut channel.
மிக அருமையான எளிமையான விளக்கம்
Bro ithu liquid propellant Ku OK but solid propellant Ku enna use panuvanga
By ablative or radiative cooling. Or both.
nice question man
That was simply said but superd. Kudos. Applause.
I really don’t know the law that tells not to burn coins. 0:23
Coz once wealth generated ,it should be transferred or circulated ,not destroyed in order to prevent the disruption in the wealth of the country
Yea bro
But govt can ban currency which would not ever cause any disruption in economy
@@faiz7041 sure each and every wealth is created by other wealth in direct or indirect way will be destroyed in any some way but governments intention is to control that wastage and should be ours too...If u use non destructible wealth it will be stored in the hands of few...So it needs to be changed and it also to be mobilable .So we ultimately use currency in paper or coin...If we destroy it ,it leads to economic crisis because it is like throwing gold in ocean ...We should not do intentionally ...That's the point here ...Finally Y the government bans ,It tries to circulate the money properly to all and it is keep on researching to increase the life of paper and coin currency ...We should be responsible while handling currency ...###Money is value of trust rather than measurement of buying power in my pov

3200-232=2968 degree celsius heat enga pochu bro????
Yaar saami nee ivallu naal ah enga iruntha
2nd law of thermodynamics ,
-232°C already oru metal mela flow aaitu irukum bodhu heat increase aaga late aagum and 3200°C odane varadhu slow ah dhan achieve aagum ,
Eg: neenga milk boil pannumbodhu unga burner la fire vandhadhum unga boiler heat aavadhu konjo time aanadhum dhan aagum , adhuve unga milk cold ah irundha (5°C-10°C) unga boiler heat aaga romba Neram aagum ,
So avanga 3200°C ah subtract panala , 3200°C reach panra time ah increase panraanga ,3200°C ah nozzles reach panradhukulla adhu stratosphere ah thandidum andha region la temperature (-3°C to -90°C) irukum so heating process delay aagum😊
