Entropy Balance
I've made a lecture style video on entropy using prezi, feel free to go back and replay each section to fully understand each bit. Prezi is also free for students, and I will be attaching the file for it on this page, As well as it converted to a PDF.
After understanding the topics in the video, have a go at some questions, specifically week 7's tutorial sheet.
Here are the useful equations you will need to know:
I've included all the ones I've used here but you can derive most of them from the ones listed in the useful equations section
Entropy balance in words
Algebraic Entropy Balance
Mass transfer of entropy
Rate of entropy change due to mass transfer
Entropy in a mass
Change in entropy for a system
Rate of change in entropy for a system
Entropy change in a adiabatic system. (No entropy change due to heat transfer)
Entropy change in a Closed system
