48 uL per power stroke... lets round to 50 uL
1/4 cycles are power stokes
say 2000 rpm? ... then ...
500 power strokes per minutes
50 uL * 500 power strokes /min = 25,000 uL/minute
= 25 mL/minute, or you could say
40 minutes per liter...
thats the basic idea, change the numbers to match your rpm and engine (2 stroke or 4 stroke)
The above number, 50 uL per injection cycle, is based on the hydrogen content of water being 2.5x gasoline, you can see this calcuation done out in full in the independent report, it's not a magic calculation that has anything to do with the WFC tech, so it's the same as saying a diesel engine uses 20 uL per injection cycle of Diesel fuel... which would vary depending on your engine
