Heat Engines, Thermal Efficiency, & Energy Flow Diagrams - Thermodynamics & Physics Problems

This physics video tutorial provides a basic introduction into heat engines. it explains how to calculate the mechanical work performed by a heat engine using heat flowing from the hot reservoir and the heat energy flowing into the cold reservoir. It explains how to calculate the thermal efficiency of a heat engine as well as the power rating in kW and horsepower. It discusses how to calculate the mechanical work performed per cycle and through many cycles given the energy of combustion of a fuel. This thermodynamics video tutorial contains a lot of examples and practice problems for you to work on.

I cannot thank you enough, this channel is a tremendous help with my studies.....I am grateful to learn from you

[@Tomahawkbeast]

He doesn’t get enough likes.

[@TheEngineerBlueprint]

I came to this video by recommendation of ChatGPT

[@ricardoestrada9422]

Thanks to you I passed my classes! now get to graduate

[@sofiadeleon6759]

I reaaally recommend this channel! The video help me to understand and to report the lesson properly! Thanks!

[@calxmw5781]

Thank you! Your recent content aligns perfectly with what we are learning in my physics university course. This is the last topic on our final exam and I really appreciate your videos. ~from fellow ochem student

[@virus117xX]

Thank you bro. I have no knowledge of this but know basic math, wich is enough just to keep up.

[@theresia1845]

Not me watching his videos before my class 😂💀

[@behpeak6837]

so touching for an excellent video

[@surakshanaacharya7771]

9:08 why would you use 24000J instead of 6000J since it does 6000J of work?

[@Duhans700]

Thank you so much! This video help my test.

[@annahwanet767]

Ya me too....he is genius

[@chris_chris_sa]

Wow I learned powerful knowledge in 20 minutes. This videos are powerful

[@jacattac9556]

goat for science olympiad

[@thompsongift7776]

Thanks your videos has been very helpful

[@nardinomuchongo6080]

Oh! man thank you a lot may the Lord our God bless you.

Helping in my Indian RAILWAY exam

[@うな-p5i]

hi, im just asking, at 11:51, does it really get 8333J, because my calculation got 833,333.3333J... 18% mean 0.18 right?

[@newmoviesclips8011]

at 11:25 why did you have put % sign along with 100 from right side?

[@tendochristine4941]

Thank you for teaching me l got an A in the math you taught me

[@InspiredLivingChannel1579]

Thank you. Can you do a video on sources and generation of electricity and help in some tutorial questions and solutions

[@anjansalaver6052]

A carnot engine operates between temperature of 1000K and 300 K the engine operates at 2000rpm and develop 200kW. The total engine displacement is such that the mean effective pressure is 300kPa Determine (a) the cycle efficiency (b) the supplied (c) the tota engine displacement? Do you have any tuts on this type of problem? And what is a gas is supplied to the engine like helium? Any sample problems?

[@Trisontraileryt1738]

What is the most common topic in all of physical science?

[@miguelsantillan7303]

This saved me about 30 minutes ago

[@eremika6175]

How did you get the 44.4%

[@andilemthonti]

thank u so much helping

[@adriang.4628]

do you use paint?

[@jaarryifleshblood315]

So your saying the cooler the engine the more work to the engine..?

[@lars8265]

The delta determines work. Thermal works on cold like dry or even more exotic and potent ices thAn co2!

[@eremika6175]

How do you compute contant reservoirs temperature which is Tc and TH? Been trying to search but it's showing up water and pressure

[@eremika6175]

Am I going to use the formula of Sadi Carnot? (1-, T2/T1) × 100%

[@annahwanet767]

I ddidn't have time to tell my sincere thanks ....I'll let u knw after ze exam

[@trevor7821]

How did it go?

[@gerardberunio3643]

what app are you using to write those things?

[@j.jokkwan4127]

For 5 minutes, the temperature of 20 liters of water was warmed from 20 ℃ to 60 ℃. And the gas consumption for 5 minutes was 0.093 m3. How much is the thermal efficiency of this hot water heater? However, conversion to Joule from a calorie is 1cal=4.18605J. And a calorific value of city gas of Tokyo is 45 MJ/m3. Can someone help me ?

[@ivanl1857]

awesome！

[@ሰንፔር-በ1ቨ]

So how it could be efficiency =1 over h ? ? ?

[@MarkoHR]

"Watts... I mean Work..." feel ya man

[@dfgf7782]

did you feels his "inside" ? wdym

[@vibinjacob4610]

Useful mechanical energy which can be used from rotation of shaft.

[@universe5904]

Thank you you are genius

[@cheeseball5066]

THE GOAT 🔥

[@mohammedrizwan420]

Thank you! very useful indeed.But I'm confused with the last conversion part. :( 4 (a)

[@bilgekyran9902]

what is your major? what kind of human is this. is it the 4.0 gpa man that has never existed? every topic but all I found was one of your videos. I go crazy

[@makomiravic3798]

Thank you

[@niklasbla9076]

awsome!!!

[@BolMawien-tp9qx]

❤ workdone

[@zer8960]

luv ya vids

[@chi_besh2812]

Omo thanks 🎉

[@tturi2]

the non SI units were fine i guess haha

[@manejago7064]

you got 3 mil subs and doing this for years still you cant buy a fricking better mic!

[@LionnelMebenga]

Thank sir please

Depending on altitude and composition of released products the environmental heating claimed in minute 13 is specious. Bermuda grass is largely responsible for loss of planetary ice as the water vapor pollution from sprinklers at low altitude where no rain or clouds but reduced losses to outer space nearly doom us alone. We have to make ice stop burning allow uranium rich nations license to produce daily megatons of frozen air immediately little else can reverse melting yo
