Carnot Cycle & Heat Engines, Maximum Efficiency, & Energy Flow Diagrams Thermodynamics & Physics

This thermodynamics / physics video tutorial provides a basic introduction into the carnot cycle and carnot heat engines. It explains how to calculate the maximum efficiency of heat engine which is equivalent to the thermal efficiency of an ideal carnot heat engine. This video contains energy flow diagrams that will help you to visualize the transfer of heat energy from the hot reservoir into the heat engine and then to the cold reservoir. This tutorial also discusses how to calculate the mechanical work generated by a carnot engine. It also covers the four steps of the carnot cycle which consists of an isothermal expansion, adiabatic expansion, isothermal compression and adiabatic compression. This thermodynamics contains all of the formulas and equations needed to solve the practice problems presented in this tutorial.

I hope YouTube pays you well because you’re out teaching my professor

[wolvsongthechosen]

This guy has helped me pass all my upper courses of chemistry he is a life saver, thank you.

[ClydeBuka]

You explained better than my lecturer thankyou

[rheaplawat]

i am so grateful for this elegant and simple explanation of the carnot cycle. it saved me from losing so many marks in my exams!

[charlesmutuku]

you made the carnot cycle easy for me to understand, i passed in my thermodynamics exam.thank you

[bethuelopety]

Less than a week before my exams I I just learnt more than what was taught over a semester

[guguruseto]

absolute chad, thanks mr. organic chemistry tutor. If I pass my thermodynamics class, It's mostly thanks to you!

[areebahjamal]

This really helped me connect all the ideas together. Thank you so much!

[radheykrishna]

You are excellent bro! Even my lecturer isn't able to tell in this way! You are a great person!

[jordanmwandila]

Last week our lecture gave us an assignment to explain about the Carnot cycle and I took note of exactly what our organic tutor is explaining guess what, , ? I got an 100 %

[srw]

Thank you for your valuable lecture! I'll do my best in the finals.

[hiwotberhanu]

I love u dude I was dealing with a hard problem with carnot graph I was trying the question for 2 days and now after ur video 🤗🤗🤗I came up with the answer😍😘😘😘

What majors did The Organic Chemistry Tutor select at college because everything you explain it becomes clear . Everything Maths, Biology, Chemistry, Physics, which ones were your majors ?

[Forexmotivationss]

My school fees needs to be sent to this man!

[omeransari]

Your Thumbnails alone are so informative; respect mann <33

Exam time in 18 minutes, let’s see what we get

Hi, at 18:08, I think you missed a negative sign. Q(c)=-nRT(c)ln(Vd/Vc) Your videos really help a lot!!

[Nick-mqiq]

Something about your voice just puts me in "learning mode". It's so soothing, and clear like I can understand what I'm being told

[fuge]

thank-you, studying for thermal physics and we are using Daveil V. shreoders book, this is a great complement to it.

Great! I was looking for how to calculate the net work.. It took only few minutes💯💥
