 For flow and PSI, you could put nitrogen in the equation.  Flow and Pressure
only are not density related, only unto the material properties to both
examples, hence a constant.  Here the fluid is O2, density is irrelevent to
an absolute boost measuring device.  9psi is the opening pressure of a given
valve @ xCFM.  That doesn't increase to 14psi with warmer air @ xCFM.
 
 
 Maybe my next post can redirect the whole issue.
 
 Everyone is right, except when applied to the bypass valve
