As fuel pressure increases, the volume of flow increases as a function
of the square root of the ratio of the pressures.
Example: 

	 --------------			   -------
	 | new pressure			   | 60psi
	 | ------------  = vol increase =  | -----  = 1.22 times old flow
	\| old pressure			  \| 40psi

The volume delivered is linear with injection duration.
