15.8 Heat Engines

This video covers Section 15.8 of Cutnell & Johnson Physics 10e, by David Young and Shane Stadler, published by John Wiley and Sons. The lecture is part of the course General Physics - Life Sciences I and II, taught by Dr. Boyd F. Edwards at Utah State University. This video was produced through the support of the USU Physics Department and the USU Media Productions team.

sir is always majestic while explaining the wonderful concepts,

[newagarwalcomputech]

Awesome, one of the best thermo video on youtube

[GiaDoan]

It’s people like you that contribute to saving our planet and species!

[francescocuccu]

Amazing! Thank you very much for your great work

[djpalpro]

Lot To learn, but this was brilliant guide and Well told 🤩 thank you 😊

[josenegrete]

And with this simple example my statistical mechanics textbook makes sense...

[saanvi]

Never saw something like this awesome explanation
Thanks a lot sir
❤️Love from india

[princejaman]

Great video sir understood it thank you 😊

[basirumbyeal]

Well explain but I want to have more contact with you if possible please

[al-kareem]

wow amazing explain i m big fan of you sir

What is the maximun horsepower you can produce in that little steam engine?

[gaetano]

Explanation of String engine working principles a bit off, great video none the less, thank you!

That's a combustion engine, not a heat engine!

[dominiccoyne]

Literally anything that produces heat as a byproduct could turn the lost heat energy into practical work by strapping a heat engine on top of it

Eg. A coal fired powerplant is only 33% efficient. Strap one of these bad boys on there and you've got a lot more bang for your buck fuelwise

I drew a basic diagram of the concept it's a shame you can't post pics

Most of what he says is complete nonsens. The heat in a combustion engine is a incidental by product it can not use and must remove by the radiator. It is the pressure caused by the explosion that pushes the piston down, nothing else. If it could be done with no heat it would work even better than now. ICE is not nor has ever been a heat engine.
A steam engine is fairly easy to understand. Boil water get high pressure steam then push a piston with the steam. Boiling of 1 gallon of water turns it in to 1800 gallons of steam. Contain it in a smaller volume and you get pressure. Boiling water in a sealed container is verry dangerous as the verry high pressure can cause it to explode, several steam engines did that in the early days.
The sterling engine IS a actual heat engine designed by rev Sterling in England but the large "piston" is only used as a air displacer to move the heated and expanded air away from the heat source so it can cool and contract. The small cylinder on top do have a piston that both gets puched by the hotter air and then pulled back down as the air cools and contracts.
The thermal "generator" running the fan is in fact a Pelletier element run in reverse, they transfer heat by a semi conductor as a solid state heat pump when supplied with power. They are good for some type of heating or cooling but with moderate to low efficiency. When heated and cooled they instead give of electricity but at verry low efficiency.

If he graduated college he should be forced to give back his diploma and get a refund. Do not trust a word of this man.

Great video, did you have some drinks? Your speech seems slurred and your slow reflex to turn off the whistle was tortuous. Cheers.
