Re: fms injectors what flow(psi) are they rated at?

Everything I've seen indicates they are flow rated at 2.7bar (= 39.15psi).

To correct for a different operating pressure:

New flow rate = rated flow rate x (Pnew/Prated)^0.50

Example, running a 30# FMS injector at 43.5psi:

30 x (43.5/39.15)^0.50 = 30 x (1.1111)^0.50 = 30 x 1.0541 = 31.62 #/HR
