- The video simply explains the Rankine Cycle in Thermodynamics. Rankine Cycle is one of the cycles in Thermodynamics that contributes a big impact on our society by providing electricity in the Industries and in our Residence.
Rankine Cycle in Thermodynamics is also one of the major subjects in the Engineering courses or curriculum and this video teaches you the basic things about this cycle. Rankine Cycle is a fun thing to study.
Rankine Cycle was named after a Scottish polymath and Glasgow University Professor, William John Macquorn Rankine
It is a Vapor Power Cycle
Power Cycle is a cycle that uses heat to generate work and since it’s a vapor cycle, it uses the vapor phase or in this case steam to rotate the blades of the turbine.
It actually utilizes the heat energy contained in coal, oil, or natural gas and then converts it into mechanical energy and eventually electrical energy. Which of course provides electricity in our city and in our homes.
One of the best definitions for this cycle is that it Closely describes the process of Steam Turbine Systems and is Derived from the Carnot Cycle. The most efficient thermodynamic cycle tells us that power is dependent on the temperature difference between a heat source and a cold source, which is our surroundings. The higher the difference, the more mechanical power can be efficiently extracted out of heat energy.
So now let’s talk about the variants or the Types of Rankine Cycle.
We have a REHEAT RANKINE CYCLE, it is a cycle which we introduced the exhausted steam back into the boiler to reheat it)
We also have a REGENERATIVE RANKINE CYCLE, we bled a part of the steam into heat exchangers to preheat the feed water before entering the boiler)
There is also an ORGANIC RANKINE CYCLE, which uses an organic high molecular mass fluid with a boiling point occurring at a lower temperature than the water-steam phase change.
A SUPERCRITICAL RANKINE CYCLE is also one of the types, Water is the working fluid and it is operated at above its critical pressure.
So those are the types of Rankine Cycle, but here in this video, we will only discuss the most basic and fundamental of this cycle, the IDEAL RANKINE CYCLE.
We must be aware that this operates slightly different than the REAL RANKINE CYCLE
This is a REVERSIBLE CYCLE, common sources of irreversibilities are neglected such as frictional pressure drops and undesired heat transfer with the surroundings.
Constant pressure or isobaric process and constant entropy or isentropic process is used for the equipment involved in this cycle.
The working fluid is WATER, it will undergo a closed-loop and will be reused constantly
So by the way Why do we use WATER as the working fluid?
Well, simply because it is NOT TOXIC, NOT REACTIVE, HIGHLY ABUNDANT, LOW COST, and GOOD THERMODYNAMIC PROPERTIES.
To make a Rankine cycle, we need 4 processes (Process 1-2 for the Boiler, Process 2-3 for the Turbine, Process 3-4 for Condenser, and finally process 4-1 for the Pump).
Watch the video of Rankine Cycle to learn this cycle in a simple and fun way.

Thank you!

The illustrations are so refreshing to look at and learn after the hours I've spent reading books. Amazing work! Thanks youtube :D
Thanks man! It's our pleasure. 👍😊
The vid is great. But god damn the background music is driving me nuts....
Yes sir! We have that covered and that would be our major improvement to more engineering topics to come. Thank you for your support!
Video is great ❤️👌.i think the background music is also nice
alan perera Agree, Music added some nice chill vibe to the vid. Great work in general
Dear friends pl kindly see my next video I will play Thanam technique Raga Ravathi please give good coments tq
Man music can be good in UA-cam videos I got it but not a music in a loop when you try to understand a thermodynamic process. Thanks for the video anyways :D and also good animations btw
Thank you for the idea sir, and yes we apply what you said on our other videos.
This is so amazing, detailed, and clear. I'm so grateful for your content!
Thank you so much for your kind words. We are so grateful with your support. 😊
that music is doing my head in
Ungrateful
Im taking applied thermo and this video helped a lot!!
absolutely fantastic videos! i am a 4th year engineering student doing my graduation thesis and this video brushed up my long forgotten thermo!
I hope for flying colors and a happy graduation to your studies sir. Thank you for the support!
Such a smooth explanation........... Loved it.....
Thank you so much for the easy explanation and the illustrations! After watching this, I finally understood the basics of the Rankine cycle a lot better than from my professor's confusing explanation. The graphics were amazing and I actually felt that the music infused the video with a positive vibe, making the video more entertaining to watch. So, once again thank you for sharing such informative and creative content!
Thanks man! It's our pleasure. 👍😊
know it clears confusion in my mind, thank you !!
It's our pleasure.
What does the S represent on your S vs T graph? If it's entropy, how does entropy decrease at all (3 to 4) over the condenser?
this is a great video, way to make a complex topic seem so simple
Thanks man! It's our pleasure. 👍😊
this is a great video
Thank you so much for the easy explanation and the illustrations
You are very welcome Omar.
Detailing is very clear
which software you use for animation purpose
Great video! Does the pressure change inside the boiler?
Great ! Thanks
you make it really simple in understanding. Can u pls explain organic rankine cycle same as. thank you
I dont get it thedigram 3 to 4 shows the constant temperature i mean the straight line,but condenser to pump the temperature is decreased compared to the inlet of the condenser how???can the line to 3to4be straight??
Very nice and clear
Thank you so much ❤
Well Explained ❤
Sir why gearbox and coupling used in steam turbine????
"there's no pump that can pump steam so we use a condenser" this was great
Why would you even need to waste energy on the pump. There should be a thermosiphon effect.
@@David_Mash i would assume relying on the thermosiphon effect by itself wouldm't generate enough pressure to allow the steam to reform
Recap for the video, you should've been explaining the important parts with more feelings, this is what differs a good tutor from a tutor. I had to re-watch some parts. Nice job and since you are a young fellow engineer, I hope the best for you. You've been useful for me to understand whats going on :)
Cheers to all of the Engineers in the world. 😊
Really easy to understand! great video.
Thanks, hope our video helps you understand in the easiest way.
The "turbine" featured is actually a compressor but, besides the detail, great video!
How?
Yes, you are correct. We will be editing this video in the future.
awesome video! straight to the point- this was a good review for my thermal systems design class
That is our goal when making videos. Easy and straightforward.
great explanation , but music is too loud
thank you bro ❤️
GENIUS!!!!
Thanks man! It's our pleasure. 👍😊
Can someone explain what kind of feedwater pump can handle this kind of temps and achieve bigger than boiler pressures? Can you use a smaller turbine working as a pump directly connected to the turbine shaft?
Brother, remember that feedwater pump must have higher pressure than your boiler because that's how Second law works. Also, there are main turbines that have 3 types of turbines connected in one shaft (HP, IP, and LP Turbine).
@@EarthPen I know this already, but the main question was about the pump.
Thanks boss
Thanks
Thx...😍
thanks for this great video
It's our pleasure. 👍😊
Why did u stop uploading more videos...You r doing Great.. Please Continue your Work👌👍
Sir this kind of comment is our inspiration. Definitely we will be uploading more videos soon! Thank you so much for your support.
Hello. In the condenser, when the temperature drops, why doesn't pressure drop too?
I hope I can answer it in a very simple way. But here it is, Heat Exchangers does not drop their pressure ideally since we are not compressing and expanding a fluid.
@@EarthPen Makes sense, thanks for answering!
nice video. keep it up!
Thank you! We will be uploading more fun videos soon!
Clearly understood
Thank you for your support sir
Nice
Well explained
Thank you for the support sir!
Thank you sir
Thank you for your support man
you are great! looking forward to your video.
Thank you so much! Yes actually we are currently making other fun engineering videos.
Great vid, easy to follow 👍
Thanks man! It's our pleasure. 👍😊
This was a great explanation!
same systems are used in solar thermal plants to make electricity from concentrated solar energy. you don't have to have combustion systems
also geothermal is possible.... it does not matter where the heat comes from... admittedly fossil fuels make is very easy to provide this heat, but are we happy to live with the consequences of continued fossil fuel usage... in saying all this... thanks for the very instructive videos... they help me teach a lot!!
thankyou sir ...we need more and more videos regarding mechanical concepts pls support.
Thank you so much for supporting our channel. We really appreciate it.
thanks you sir
No problem sir! I hope we have provided you with what you have been looking for with this topic.
excellent...
Thanks man! It's our pleasure. 👍😊
Nice sir
Nice explanation 👌
Thanks man! 😁
0:46, felt snubbed as a nuclear reactor operator when it didn't mention uranium fuel. Nuclear power plants also deal with the Rankine cycle.
Awesome
Thanks man! It's our pleasure. 👍😊
4:25 Not converted to superheated steam. But only saturated steam
Process 1-2 as i know isentropic compression in a pump. But i not see in this video. cmiiw
perfect a closed loop cycle now just replace the water with a low boiling point liquid and Bam higher efficiency bye needing less input heat this is what ill use for my fusion reactor prototype. I have four vids up about it.
I think the formula of the power needs the mass flow rate but not the work itself. Please correct it
Yes you are totally correct my friend. The all of heat and work on the formula for each process should be "rate" and it seems we have not put a "dot" above it. Anyway, we are going to edit it soon. Thank you so much for correcting us.
I don't think the heat source has to be coal, oil, or natural gas. It could be any heat source, such as geothermal, molten salt from concentrated solar, biomass, etc.
Yes surely it is. Thanks for your feedback

I used to teach thermodynamics and it is one of the most badly explained topics in science. I think it is a legacy of the people that were pioneers in the field. They happened to be awful teachers that came up with bad explanations which have been repeated from one generation to the next. This is a shame, because thermodynamics is a wonderful subject that can be incredibly useful.
H is enthalpy, I'm sure the guy mentioned it as entropy
Excellent engineering explanation
Thanks man!
thank god for the advancement of auto-generated subtitles. The accent is so difficult to understand (+music). AI can distinguish the words better than I can. What a time to live in
Add efficiency of rankine cycle
The video is cool and appreciate the hard work , but the background music does not give me the chance to focus.
Actually, we are planning to make a better version of this. But thank you for your suggestion. 🙂
Energy convert no directly mechanical to electrical but chemical to thermal after to mechanical after to electrical
Good but a shame the music is so loud. I can hardly hear the speech.
Please remove Music
we need to know all cycles
Please subscribe and explore our channel. Hopefully you can find the cycles you arr looking for. 😊
🎉
The background music is very irritating. You should upload such types of videos without music.
You confused enthalpy for entropy. Good video though
The animation is very helpful but the music could have been avoided or at least kept in a lower volume (because the narrator's accent is already difficult to understand).
The music is hellishly distracting. Could you repost without the background noise?
Actually we are planning to have a better version of this video. But thanks for your suggestion. 🙂
bro you have used wrong symbol for turbine
Why do I hear people in your background?
Yes, because at the time of recording for this video, our audio is not good. Atleast not better than our recent videos.
This appears to be a good, informative presentation but I stopped watching after a minute due to the distracting music. Imagine going to a lesson and as the lecturer is talking there is music in the background at the same volume as the speaker. There are some excellent comments here but as a mature learner it is too distracting for me. IMHO if the info is well presented, you don't need music.
Idk what this is I'm just interested cuz of my last name
Fucked up with music
Very good except for the brain washing music 🎉
Thank you so much! Yes we are currently studying the approach of audio background.
Your video illustrations is not enough, diagrams for T-s and P-v needed
How I wish we could show all of the things that we want to, but it would make the video longer than it is now. That is the reason why we try hard to explain every topic as easy and as simple as possible. 😁
But thank you for your suggestion. 😊
Me too - gave up couldn't stand that music.
Too fast. Not enough time to process the information. Gotta pause a million times to rehear a concept and process it
Very interesting course but I have to advise you to write down every single word.. because what do I say your language!!!! Extremely hard to decrepit. Sorrrry. But thanks anyway
Yes my friend, thank you for your insights. Actually we are making adjustments now for our video to have it more understable and that includes our audio. Thanks!
Great! Can't wait
Please pronounce the words correctly and completely. You are swallowing half of the words and rest half is gone with that music
Thank you for your suggestion. Actually that's our very first video and we are still continuously improving our audio department for that same matter. But you're feedback is really appreciated. Thank you so much!
Thank you so much l will try my best
Could u please remove the music in the background otherwise the content is good.
Thank you so much. This was our very first video and apologize for the unpleasant audio background. However, our videos uploaded after this one has a better audio background compared to this, as we have improved our audio department.
Thank you once again, and have a nice day.
How about you do this video with someone who speaks English?
please stop putting on music, I barely care hear you
Kuddos for the presentation. An easy way to understand for us students and also very informative. Thanks! I look forward for more videos :D
Thank you!
Thank you for making this topic very understandable and fun at the same time 😊 Hoping for More videos soon 😉😊
Your welcome!
That backwards turbine is really annoying.
I like the style of your video discussion. I hope you can make more of this.
Yes, we will. Check out for more videos soon :)
Nice and understandable way of presenting this topic - thanks for the video
Thanks man! It's our pleasure. 👍😊
Looking forward for more videos. Good job. 😊
Thanks man! It's our pleasure. 👍😊
Thank you for the nice discussion
Thanks man! It's our pleasure. 👍😊
Excellent explanation. Thanks
Thank you so much for the appreciation sir. We will be uploading more videos soon!
Could this be a perpetual motion device if the device is generating it's own energy for evaporation and condensation?
Dude, this kind of thing doesn't exist. The carnot efficiency (just based on the temperature difference, ignoring all the losses) never gets 100%. Beside that, there's something called "the second law of thermodynamics" that says that the entropy of a closed system ALWAYS increase through time. In other words, you cannot create a perpetual motion or infinity energy device.
thank you for your effort
Thanks man! It's our pleasure. 👍😊
Very nice make videos of regenerative, reheat cycles... This is Easy way to understand these topics 💞❤️❤️
Thanks man! It's our pleasure. 👍😊
