Hi, I have a fluid dynamic question. I need to know the volume airflow rate (cfm) for head loss calculations in my CTIS (central tire inflation system). My goal is to use this info to come up with an analytical model of the system. Our facility has an air compressor that is set to 72 psi. The inlet diameter of my system is 0.013 ft, but it has multiple bends/components and diameter changes throughout the rest of the system. The measured backpressure for the entire system has been shown to be around 7.5 psi. Anyone have an idea of how to find out what I'm looking for?
