We often get questions on here about flow rates. Some reply in litres per minute or Veristream settings.
These all vary according to the system being used.
There is one simple way we can measure flow rates, and a way everyone would understand.
Hold your brush 6 ft above the ground, and measure in feet the distance from the brush to where the water hits the ground.
On my preferred flow rate, using this method, my water hits the ground about 7ft away, that's using 2mm pencil jets, so we could say we were working with a 6,7, or 8ft flow rate.
This method would apply to any system being used, as long as you try it in a spot sheltered from the wind. does this make sense? what do you all think? Dai

Good idea,when someone ask`s me about flowrate that`s exactly how i would describe it.

Personally I prefer litres per minute as that is easily measured by nicking my wife's measuring jug and seeing how much goes in in one minute. (Which ever brush/jet I use.)
-
What about this one, we could have a system of words like-
Bit low
Too high
Just right
Bit more
Mmmmm, not quite
GEEEEEEEEESS, turn that damn thing off!
I prefere the third one ;) (with 2mm pencil jets)

God almighty this is so simple:
Length X Breadth X Pi r squared X the square root of the pressure at source = Whatever the hell Dai
was on about ???
Come on people, get a bloody grip ;D

I have found a flaw with this method.
IT'S JUST TOO SIMPLE. Dai

You need an acronym. I suggest p, projected inflow standing standard

Dai, sorry mate, but too complicated; there's at least two measurements to be taken with a tape measure, and if you mean that the brush head should be 90 degrees to the Earth, then you require a spirit level too.
This is the simplest way:

Ok, I give up. I assumed that everyone knows how high 6ft is, the average guy being 5ft 10, I also thought that most guys have a good idea how far 7ft is, and would know if his brush was at approx 90 degrees too. I was only suggesting this as a rough guide when describing your flow rate to someone that is new to the game. Nothing scientific, just a rough rule of thumb for a new WFP guy to make a comparison between his own flow rate, and that of a more experienced guy. Dai

It's all approx this approx that. Measuring jug takes less time, less guessing, and is 100x more accurate that all that guessing in feet.

I think the measuring jug method is most practical
but I can't find one with minute measures on it.

LOL hahaha ;D
