16:03 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 22 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 0 likes 412 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 0 likes 452 plays 0 Optional Metadata - Department Aerospace Engineering
11:39 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.
