As title dipicts I'm wishing to understand the relationships between CFM and PSI in regards to Air Regulation.
For example let's say I had a compressor tank with a compressor connected to it, to fill it to 200 PSI. I connect an X diameter Air line to an air regulator, and than have its output just an open X diameter Air line.
So my question is how can I control both variables. How could I have let's say a high flow rate, but lower maintained pressure. Or vice or versa, how could I have a low flow but at high pressure.
What I understand is that an air regulator (by some means) reduces the air pressure (PSI) by having a preset (spring rate) spring that opens after what ever you set the pressure tension bolt at(or what ever means the system uses to change spring reaction/travel). What I don't see is if the CFM would change based on what PSI the regulator is at. Also another thing I don't understand is how the X diameter line falls into play. I would think the larger the line, the higher the flow. Pressure would be the same but the tank would empty faster. How can I understand this fine line and learn how to balance those numbers.
Hypothetically let's say I know how much CFM I would like to generate, and I know at what PSI I want the CFM to be at. So in the end how would I control both those variables.
Hopefully me spelling it all out will avoid missunderstandings and replies that wouldn't hit the nail on the head and end up not giving me the exact answers or where to look for them.
Thanks for all those who read this short "story" and also to those who may reply!
