what is the derivation of your 'formula' ?

Pumps.org's (aka Hydraulic Institute) definition and formula 1.2.6.3
That formula yields results as water horsepower. From there I convert to watts. 1 water horsepower = 746.043 watts.
(metric) P = Q*H*s/366
where:
Q = flow M^3/hr
H = Head in meters
s = specific gravity
The two formulas are very similar, but something has been lost in translation for one of them.
No offence Les, but I tend to trust a formula from a respected trade group more than "beer mats and slide rules". I have no doubt you can get medieval on a math problem, but I need to know why the formula is wrong before I go fixin stuff.
I would like to know for certain which one is correct before I do anything.
