The Attempt at a Solution
I am trying to understand the above ph diagram (for a vapour compression cycle), In some examples, point 1 is situated as above in the image (i.e. to the right of the saturated vapour line) and at other times it's situated exactly where I drew the purple arrow (i.e. on the saturated vapour line). I am guessing this has something to do with whether there is superheat or not but it would be great if someone could explain.
Also, in some examples there is no point 2' (only points are 1,2,3 and 4). What is the exact significance of 2'?
In examples with no point 2', we are told that line 1-2 is isentropic but in the above example where there is a 2', we are told that line 1-2' is isentropic. Does this mean that in the above, line 1-2 is not isentropic? Why/why not?
Thanks a lot
