    what's the functional difference? Wouldn't it be at a given CFM, which would indicate a very similar aspect of the restriction caused?

      It would be dependent on volumetric flow rate, but to me it is definitely worth mentioning.

      More useful would be a plot of how pressure differential changes as volumetric flow rate increases.
