3.
From the flow rate performance diagram for
the regulator, obtain the the output pressure
for the regulator at the minimum free flow rate.
Calculate the pressure drop.
4. Check that the calculated pressure drop does
not exceed the maximum allowable pressure
drop (

If no flow rate performance diagram exists, follow
the instructions in Section 6.1.2 to check your
pressue regulator.
