Trying to learn how to read compressor maps

You cannot just "pick" a point to operate at.

Ah okay what you said makes perfect sense.

Is there a chance that there is a nice table of volumetric flow rates of a 13b-rew at different rpms on the internet, or should I just try to calculate a table like that myself?

The other thing that is a little iffy is how someone can say 65lbs/min is required to make a certain hp. It depends on temperature as much as mass flow rate. Guess I need to look into it a little more.

Edit.. crap, no it doesn't!! i had my mind set that lbs/min was a volumetric flow rate. My bad. and its only been 2 and a half months since my last fluid dynamics course =P
