I really like your Filipino accent. It's so pleasing to the ears and makes me proud that there are a lot Filipino scientists who can be as good as or even better than those in other countries. Thanks to you, I have made it my habit to remember only a couple of words for science laws: "Heat is energy" for the first law of thermodynamics, and "high to low" and "perfect is impossible" for the second law. You are the best! Keep doing what you're doing.
The challenge is the materials. Those required would not be economically viable as lesser would be subject to a short service life/high maintenance cost. It’s great for inspiring those problem solving minds and discovery’s of the future.
One question please : In carnot cycle, Why don't we replace the isothermal process into isobaric PROCESS? Because, the isobaric gives you more (work) than isothermal does?
Because through isothermal expansion we are giving the gas the energy with minimum energy dissipation,that is we are passing our whole energy to gas without energy wastage,in other words heat energy is stored in gas as potential energy of gas molecules.but in isobaric process,more energy will be transferred as Kinetic energy and there will be dissipation and wastage of energy.you should focus more on basics
Is it the flywheel that keeps going Carnot engine cycles? Is it the Heat source that drives the process 1 2? Is it the Heat Sink that drives the process 3 4? & together with the inertia from the flywheel the cycle keeps turning? Higher temperature from 4 1 plus the addition from the source displaces out pistons? Lower temperature from 2 3 plus & heat sink during 3 4 contracts the gas and displaces the piston in?
Thermodynamics gives you bounds on real engines. Moreover, the explosion of the fuel mixture is not even approximately reversible. How can thermodynamics be of any use in designing real world internal combustion engines?
@@nijub.s.1165 How inefficient is it now? Yes, it is a good thing to know classical thermodynamics. But consider the following. If the engine you are designing operated in quasi-equilibrium, then some Carnot design would be arbitrary close to optimal. However, if that processes is far from quasi-equilibrium, operating in a Carnot engine it need not be more efficient; than the solution of optimal control problem constrained by the DE of the non-equilibrium process.
Nothing is ideal in world.. but we only try reaching that ideal level. Hence the knowledge of ideal cycle will help us reach close to it. So you can save your hard earned money
Process 1 2 Temperature should go with heat addition from source but the pressure drop from expansion makes up and keeps the temperature same throughout the process. The expansion needs to be slow to match the increase in temperature from the source to keep the the temperature constant?
All reversible processes are so called quasistatic processes, which means the state of the system changes so slow that it is considered in equilibrium or near equilibrium at all times. But ideal reversible processes are not possible in reality, which is one of the causes, why the carnot cycle can not be realized.
Reversible means that we can do the process in the opposite direction And we know that reversible process is ideal like carnot cycle So why can we do the reversible in machine like heat pump??
Reversiblity in the video you watched above has not the same meaning as heap pump reversibility. I understood what you meant. in heat pump, we act on 'a reversible valve' JUST to inverse the operationwe need (from cooling to heating OR from heating to cooling).
@@issamelhamouti4014 i understood later that there are a difference between reversibility in carnot state and clauses state . and know that reversibility in carnot means no lose in energy by friction so it is ideal
This music in the background is aweful. For some reason thousands of videos are using this same music. Would've been much nicer to watch without the background music. Also, I advice using some noise reduction tool. I can suggest Audacity (free).
This is not intuitive to me. Let's assume the engine starts the cycle from rest. This means that the pressure force pushing up on the piston and gravitational force pushing down on the piston must be balanced. If we then start the cycle and the pressure drops throughout the isothermal expansion step, what force is causing the piston to move upwards? It can't be pressure, because pressure drops below the piston, which means the upwards force should actually decrease. It can't be gravity, because the piston's mass isn't changing. What am I missing? Edit: I'm guessing it's just not possible to start the cycle from #1. If we assume there is already a huge net force upwards at #1, the pressure force could be decreasing and still result in the piston moving up. Maybe a better question, then, is where would an engine at rest show up on the PV diagram?
no, because the carnot uses an ideal gas where electrostatic forces are negligible so an ideal gas no matter how compressed will never turn into liquid.
The temperature doesn't change in the system. The system absorbs heat while expanding (isothermic). If if wouldn't also get heat from the surroundings, its temperature would drop. It's the other way around with the isothermic compression.
It would be convenient if the accent is clear....people from south Asian countries may find it difficult to understand Filipino accent.....The content is good and helps in quick recap!....thanks:)
as mentioned, the system is insulated during adiabatic process so that no heat enters the system. what happens inside then is that molecules continue to move rapidly due to high temp obtained from isothermal expansion. this movement causes the gas to expand and as it does, temperature begins to go down.

True
Yes you are right dear I am watching this channel from 6 month and this why iam fan of sir
Same .... Nothing much difference
this help me understand much easier for this topic to settle my assignment
Hii
Agreed
itu la tu
I hope it helps me too.
Thanks for this super simple and helpful video. Really appreciate it :)

How may i ask you thank you...This video helped me alotttttt ..Huge thanks for you .....
We are so glad to hear that ibrahim. 🙂
tqsm great explanation!!!
You're most welcome. 🙂
thanks for the help Bro, you make it understable. big up!
Are the four stroke engines based on this theory?
God Bless you! Thank you so much.
Life saver!
Nice explained
Process 3 4
By the same token
The compression needs to be at a slower pace to catch up with heat removal for the temperature to stay the same?
Thanks a lot it was amazing explanation 🎉🎉
Is it the flywheel that keeps going Carnot engine cycles?
Is it the Heat source that drives the process 1 2?
Is it the Heat Sink that drives the process 3 4?
& together with the inertia from the flywheel the cycle keeps turning?
Higher temperature from 4 1 plus the addition from the source displaces out pistons?
Lower temperature from 2 3 plus & heat sink during 3 4 contracts the gas and displaces the piston in?
Awesome work....you helped me....thanks🙏

Because if you don't know thermodybamics, the efficiency would be even worse than it is now 🤡

When the gas particles get energy that can apply a force on the piston which makes it move upwards
Twas a nice one

Who is compressing the piston?
Matur suwun bro... Iso ngge pelajran neng kelas....
I fully support this channel😀👍
Thanks man!
good explanation
Is there any risk for gas to change its phase into liquid when its compressed in carnot cycle?
no, because the carnot uses an ideal gas where electrostatic forces are negligible so an ideal gas no matter how compressed will never turn into liquid.
4 stroke?
@@degraj418 what about car engines? Both diesel and spark ignition there is no risk too?
@@ozgurkayabas6380 well ideal gases do not exist in reality so I cannot say the same for real gases.

Very nice
Nice way to explain easily...🙏🙏
Thanks Ashpak! 🙂
Bud, try adding subtitles next time. I barely could catch your accent😂
why is the isothermal expansion the one where tempreture changes?
The temperature doesn't change in the system. The system absorbs heat while expanding (isothermic). If if wouldn't also get heat from the surroundings, its temperature would drop. It's the other way around with the isothermic compression.
Loved it♥️
Thanks man! It's our pleasure. 👍😊

That was helpful, Thank you
Thanks man! It's our pleasure. 👍😊
Nice one 🤭♥️
Helped me a lot 🥳
Reversible but arrows direction for heat engine not carnot cycle
Is right
There is no Entropy?
Infact if not for these you tube videos learning would have been difficult.
Because heat loss is not considered during this process. Without loss there is no change to complete the cycle
really helpful thank you
You're welcome.
What happens to sink source🙄
It would be convenient if the accent is clear....people from south Asian countries may find it difficult to understand Filipino accent.....The content is good and helps in quick recap!....thanks:)
Thanks 😊
You are always welcome Tandra. 🙂
Its a ideal cycle actually no cycle or process is 100% efficient
Why the gas volume is increased in Adiabatic Process? I mean it could be be unchanged. What drives this expansion?
as mentioned, the system is insulated during adiabatic process so that no heat enters the system. what happens inside then is that molecules continue to move rapidly due to high temp obtained from isothermal expansion. this movement causes the gas to expand and as it does, temperature begins to go down.
@@claricepaghasian2005 and the pressure goes down too, or does it remain unchanged in the case of PV = NRT ?
@@fernandb.6162 pressure goes down too, applying boyle's law
Maybe not what I was looking for. Equations, demonstrations etc..
