I have Delta P vs. Flow Rate data for air flowing through a particular valve. The unit of measure for the flow rate is scfm. Now, I know that scfm is the mass flow rate divided by the density of the fluid at standard atmospheric conditions. The problem is that I want to flow He through the valve instead of air. How can I relate the test data of this valve to my conditions? Is it a simple ratio of the densities of the fluids? If so, is that at standard atmospheric conditions or at test conditions? Thanks.
