23:01 13a Heat engines 13a Heat engines	13a Heat engines Here I introduce the concept of the heat engine. I define the source and the sink. I then use the first and second laws of thermodynamics to derive the Carnot efficiency. I then point out that the… thermodynamics first law second law heat engine heat work carnot efficiency From Stephen Beck on February 4th, 2021 0 likes 0 plays 0 Optional Metadata - Department Faculty of Engineering
16:09 13g Example of throttle and HX 13g Example of throttle and HX	13g Example of throttle and HX Here I go through the two examples of a throttle and a heat exchanger. I look at the energy equation, and solve that. THen I look at the rate of entropy production. It is positive in both cases… thermodynamics irreversibility heat exchangers throttle entropy second law first law From Stephen Beck on January 20th, 2021 0 likes 0 plays 0 Optional Metadata - Department Aerospace Engineering
10:29 11b Introduction to the second law 2 11b Introduction to the second law 2	11b Introduction to the second law 2 Here I describe what is hapenning in the two videos of the kid falling off the bike and the kid falling off the bike in reverse. I describe the natural order of things beign that order decreases and… thermodynamics heat work reversibility irreversibility second law entropy From Stephen Beck on January 19th, 2021 0 likes 5 plays 0 Optional Metadata - Department Aerospace Engineering
13:28 11a Introduction to the second law 11a Introduction to the second law	11a Introduction to the second law Here I show a series of irreversible processes. I discuss how in each case high quality energy is converted into lower quality energy and that this is inevitable. I introduce the concept of entropy. thermodynamics heat work second law entropy reversibility irreversibility From Stephen Beck on January 19th, 2021 0 likes 7 plays 0 Optional Metadata - Department Aerospace Engineering
11:05 7a Overview of the Thermodynamics course 7a Overview of the Thermodynamics course	7a Overview of the Thermodynamics course Here I introduce the course, and inform student how they should be studying. I show the week by week plan . Then I go through the syllabus and pick up some of the fundamental concepts I will be… thermodynamics overview introduction heat work first law of thermodynamics second law of thermodynamics energy entropy From Stephen Beck on January 18th, 2021 0 likes 162 plays 0 Optional Metadata - Department Aerospace Engineering
11:31 11c Second law processes and the T-s diagram 11c Second law processes and the T-s diagram	11c Second law processes and the T-s diagram Here I introduce the T-s diagram for ideal gasses. I show that an isentropic expansion is a vertical upward line on this and an isentropic compression is a vertical downward line. I then show that in… entropy second law isentropic efficiency t-s diagram From Stephen Beck on March 16th, 2020 0 likes 211 plays 0 Optional Metadata - Department Aerospace Engineering
