people.eng.unimelb.edu.authrough the sand is no longer proportional to the square root of i. Darcy, in 1956, found that Q was proportional to the first power of i Q = k i A (5.4) or v = Q A = k i (5.5) where k is the constant of proportionality which is called the coefficient of permeability or the hydraulic conductivity .
Darcy’s Law and Hydraulic Head - University of Alabama

The hydraulic head, or total head, is a measure of the potential of the water fluid at the measurement point. “Potential of a fluid at a specific point is the work required to

GPM = 10 Internal Area = .304 (see note below) 0.3208 x GPM ÷ Internal Area = .3208 x 10 ÷ .304 = 10.55 feet per second
