Hello friends,
I'm trying to calculate the fill time to compress an air tank. I currently have the compressor's flow rate[CFM] at various pressures[PSI].
I honestly thought it was a trivial endeavor until I started gathering all the critical elements.
So, there's obviously flow rate changing as we increase the pressure in the tank. There's going to be a choking case for given time. There's the temperature increase as we pressurize. How can we take all these cases and come up with actual time taken.
It's a fun challenge, but I am loosing my hair trying to address all the changes that take place.
It's easy to just run the system and calculate the time, but where's the fun in that? In fact, I would actually like to be able to predict how the time would change for various ambient temperatures.
Any wisdom, pointers, directions are welcome.
