If you get 1 gallon at 1 psi loss, you will get 1.414 gpm at 2 psi differential.
There are a family of Cv equations. Liquids, Gases, Steam, SUbcritical, Choked flow, etc. Most of the major control valve companies allow at least a trial version of their sizing software to be downloaded from their website. ANy decent program runs all the checks to determine the flowing conditions and applies the appropriate equation.

The definition of Cv is clear. The fact that sizing and choosing a control valve isnt just calculating a single Cv value is something else.
