Entropy
Hi all, I am furthering my studies in the industry and seem to be battling to get a good and clear understanding of entropy. I have looked at a few videos on you tube, and a few websites, but it still hasnt sunk in deep enough, (maybe its me!) The one analogy which I sort of grasped was an example of an engine running (carnot cycle) and the person explaining said that the heat lost during the cycle was the entropy, say 15%.
Still not much substance though, can anybody explain it in a bit more "lay-mans" terms. Hopefully this will allow me to tackle the understanding a great deal better.
Thanks!

Re: Entropy
enthalpy and entropy are different things which one do you want

Re: Entropy
Enthalpy is 'available energy' - in laymans terms
Entropy is unusable 'available energy'
So, in your example, 15% of the available Enthalpy was unusable (Entropy)

Thanks Frank, makes more sense now already.
