This may not make sense but I'm going to throw it out there in hope of some suggestions. If I have a system, for simplicity say particles in water and they are subject to a flow of some kind, as the flow is increased it becomes more turbulent and the particles are flying around all over the place, the entropy of the system has increased. If I wanted to somehow quantify this in terms of entropy (disorder) then what factors would I need to consider, is there an equation that I could use and how would the parameters be introduced. I always struggled with the concept of entropy at undergraduate level so my understanding is probably quite skewed, but I'm trying to understand it a little further from an experimental point of view, if thats possible? Thanks for any help.
