12g Example of throttle and HX duration 16 minutes 3 seconds 12g Example of throttle and HX 12g Example of throttle and HX	12g 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 heat exchangers irreversibility first law second law From Stephen Beck 0 likes 73 plays 0 Optional Metadata - Department Aerospace Engineering
11b Introduction to the second law 2 duration 10 minutes 29 seconds 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 0 likes 539 plays 0 Optional Metadata - Department Aerospace Engineering
11a Introduction to the second law duration 13 minutes 28 seconds 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 0 likes 582 plays 0 Optional Metadata - Department Aerospace Engineering
11b Reversibilities and irreversibilities duration 11 minutes 39 seconds 11b Reversibilities and irreversibilities 11b Reversibilities and irreversibilities	11b Reversibilities and irreversibilities Here I show some reversible processes and show that they cannot be really created. This shows the cause of entropy.
