Hello
I have a point that I don't understand.
In open steady flow systems, we use SFEE, where there's a term W in addition to a term PV, which are different things.
When we analyse a cycle like Rankine, we always consider either W or PV, but not both. I also think that W=PdV always.
Why that difference? Do we consider cycles to be close systems?
