Hi
Whats the formula for calculating liters per minute?
I know i need to start with a bottle with a known capacity but whats the actual formula to use?

Thanks

take a bottle that is one liter an put the hose in it start the stopwatch and then fill the bottle under water and when the bottle is full of HHO and no more water stop the clock and that is the LPM. then is no math unless you have a 1/2 liter bottle or a 2 liter bottle then u have some math. it EASY!

Then comes the math... Time it takes to fill the bottle X 2

take the time for 500ml
then times it by 2
and thats the time to fill 1liter

example:

25 sec. for 500ml
x2
=50sec for one liter

then if you want you can cross multiply and find out what the exact amount of liters you produce in a minute. thats the math part.

you mean 50x60=3000 lpm

Is this correct?

Thanks

Actually you need to go the other way

60 divided by 50 = 1.2LPM

1000ml=1 liter

if you fill a 500ml bottle in 30 seconds, that mean that in one minute you will be able to fill 2 500ml bottles or 1 liter. That mean you are producing 1 lpm or Liter per minute.

Thanks for all the replies,but still not quite clear on the calc basically with the calculated result i am getting.
I will give you the actual results and then you can calculate the lpm and I will compare with my results.

It takes 1.47 sec to fill a 500ml coke bottle.

Thanks again

60 divided by 107 (seconds) = 0.56LPM.

ser456123,

1.43 seconds for .5 liter???

that would be 20.97 lpm if you have a time of 1.43 sec for 500ml that would be 1 liter in 2.86 sec. that dosent sound right. if it took one minute and forty three seconds for 500ml then then it would be .34 lpm

1 minute 47 seconds is 1.78 minutes. Double that to get the time it takes to make a liter. 3.56 minutes. 1 divided by 3.56 is .28lpm

We're all confused! LOL

Sorry for the confusion
1 min 47 sec to fill 500 ml bottle

So whats the correct answer?

Ok, I just knocked together an Excel spreadsheet that will calculate LPM and MMW for your cell:

http://www.hhoknowhow.info/~russ/HHO Calc.xls (http://www.hhoknowhow.info/%7Eruss/HHO%20Calc.xls)

Instructions are in the spreadsheet, I saved it in Excel 2.1 format so it should open in just about all copies of Excel.

WOW!!! that nice. what does MMW stand for? who would of thought that his little question would be so much work. thanks for the spread sheet!!!

MMW is milliliters per minute per watt.

So then around 1 LPM without over 20 amps is a figure to shoot for? I'm building my first HHO generator and was looking for a good goal number. I'm not too sure on the amps part."/
