Corrected gas turbine flow? how do you calculate this? it is the value on the y coordinate of this graph

also, is the pressure ratio the same as the one you would use if you were mapping the compressor?
is this the graph that you would use to determine at what point you would recieve full spool up, or do you get that off the compressor map. i can map a compressor and see if the flow characteristics match that of a motor just fine. but how can you determine when you see full spool?
