What you'll learn

  • Second law of thermodynamics

Course content

2 sections • 10 lectures • 46m total length

  • Introduction4:54

    Explore the second law of thermodynamics, defining heat reservoir, source, and sink, and examine the Kelvin-Planck statement that no cyclic engine can convert all heat into work.

  • 2.Heat Engine, Heat pump, Refrigerator4:53

    Explore heat engine, heat pump, and refrigerator concepts, and how efficiency relates to input and output, heat supplied and rejected, and temperature.

  • Perpetual motion machine I & II1:00

    Explain perpetual motion machines of the first and second kinds that would violate the first law and claim 100 percent efficiency from a single thermal reservoir, not possible.

  • 4.Carnot Theorem and Carnot cycle6:27

    Explore the Carnot cycle and Carnot theorem through a four-step process with isothermal and isentropic stages, showing that maximum efficiency depends only on reservoir temperatures, not on the working fluid.

  • 5.Reversed Carnot cycle5:15

    Explore the reversed Carnot cycle, detailing isothermal and asymptotic expansion and compression steps, entropy changes, and how a refrigerator and a heat pump transfer heat with work input.

  • 6.Carnot not possible why?0:57

    Explain why the Carnot cycle is not possible in practice under the second law of thermodynamics, due to irreversibilities during compression and expansion and the realities of piston speeds.

  • Clausius Inequality2:26

    Understand Clausius inequality: for any closed-cycle, the integral of δQ/T ≤ 0, zero for reversible cycles and negative for irreversible ones, linking to second law limits on engine efficiency.

Description

This course provides an introduction to the most powerful engineering principles you will ever learn - Thermodynamics: the science of transferring energy from one place or form to another place or form. More specifically, we will cover the topics of Second law analysis; Heat engine, heat pump, and refrigerator. We will cover the basic principles of Carnot theorem, Carnot cycle, and reversed Carnot cycle. Carnot cycle not be realized in practice. This class is very important for many types of engineers. I have designed the class so that anyone who is interested in learning Thermodynamics can learn. This course will be greatly helpful to all college students who are taking Thermodynamics or will take it in the future. I can help you pass and be a success! But this is also great for anyone who wants to be more educated about energy - a very important topic these days! I stay away from overly complicated theory and give you both the how and the why. You will understand Thermodynamics with my help!

Course format: The class consists of lecture videos, which average 8 to 10 minutes in length. There are also quizzes at the end of each section, which includes problems to practice your analytical skills that are not part of video lectures. There are no exams.

Who this course is for:

  • Beginner thermal or mechanical engineers
