Also assuming 6mm ID for the Hydrocool vs 1/2" ID for the "US" system.
Remember, that the block's characteristics also has to justify the use of the smaller ID tubing, and the corresponding increase in system-wide pressure-drop as a result.
It was just a roughish approximation.
Remember, the argument here is that small ID tubing + weak pump can be just as competitive as large ID tubing + strong pump, or at least be good enough to not bother with the large ID tubing + strong pump scenario. Upon making the coarse assumption that the two systems are using the same radiator where the radiator performance is essentially equal for the two different flow rates (or perhaps the increased performance of the radiator at higher flow rates matches the increase in pump heat and is thereby essentially equal in performance to a smaller pump scenario), then really it all hinges on the performance of the block and its characteristics to carry the argument on the benefits of small ID/weak pump being good enough to not justify the use of larger ID/stronger pump.
