To do it properly you really need to measure it.
For a "ballpark" though. Classic flow mechanics tells us that the level of flow resistance is proportional to the flow rate squared (P = Q ^ 2). This doesn't take into account turbulence and boundary layer conditions though.
For a fairly decent ballpark equation to extrapolate from OC.com's results I've personally found that P = Q ^ 1.85 offers a pretty decent approximation across the typical range of flow rates seen in water-cooling. P = pressure. Q = flow. Not as ideal as having real data, but when given a single pressure/flow point like OC.com I personally found it to give a fairly close ballpark curve.
