I can do that one for ya, Dr. Pelican. Quoted straight from the Kinsler
Fuel Injection catalog, which I have close by: (I figured you'd want an
"authoritative answer" B):

"Pressure rises as the square of the flow through an orifice, so to
double the flow through a jet or nozzle takes four times the pressure:
	New_Press/Old_Press = ( New_Flow/Old_Flow )**2

If we know the flow of a jet or nozzle at some pressure, we can figure
the flow at the new pressure:

	New_Flow/Old_Flow = Square_Root( New_Press/Old_Press )"

from Kinsler Fuel Injection  Supplement #29, page 10-S

There you have it.
