Hi everybody
1) what is the weight or volume of water per m3 relative to humidity?
2) with an annular surface of 45mm² and a depression of 500mm of water; How much air do I want?
3) What's in the water-soluble cutting oil, because in water doping (dilute to 3 / 100) weird things happen
Thank you to those who know and who will have the courage to respond

I hope we don't have to answer everything: too bad, I will only have a third of the points
the maximum suction of a water column is of the order of 10,65m (1065 millibars) at sea level, when the weather is good.
your 500 mm X 45 mm² are therefore approximately 22500 mm³, either 225 cubic centimeters or 0,225 liters
the fact of being annular does not matter, since you gave us the surface, except a little capillarity, but would have to see the real dimensions and the material in which the pipe is made.

Hello,
well then, i will answer the first question:
The% hygrometry is the capacity of the air to absorb a quantity of water at a given temperature,
The T ° (therefore the density of the air) allows a significant relative variation of this quantity of water.
this amount of water can be read on the psychrometric diagram
See on this site not badly done at all: http://nicole.cortial.net/complements/p ... sychro.pdf
For example;
air at 20 ° C at 50% of Hygro contains 7.5g of water vapor and can absorb up to 14,8g at 100%
If this air is cooled to 20 ° C and to 50% at less than 9 ° C, this water vapor will have to condense, because the density of air at this T ° no longer allows to contain as much water
This is the reason why air is dehumidified with air conditioners.

Hello ZAC
What does 'weird things' do? (this is a test I wanted to do). Do you have a brand a reference?

Hello and Thank you
in the case at 20 ° at 50 / 100 and 7.5g, for what volume of air?
great site but I'm still going to get a headache to apply all the formulas and have a concrete result.

PS: how do you get a nice percent with the keyboard?

Hello
the brand "Heler" a small local producer who has to be content with packaging. appearance, after mixing, normal cutting oil; milky white !!!!
the odd thing is an increase in consumption of "water" and a couple simpa; in short, the van runs alone.

Hello
solube oil, alcohol, soap in small quantity makes the water wetting (finer more penetrating)
pure distilled water is not ideal for a reactor the water must have certain additives, the water pumping in a well or a river contains impurities. With a carburetor, a little dish soap also changes the way.

The site allows you to learn how to use the diagram.
You just need to read the psychrometric diagram; it allows to know the Qute of water in a volume of air at a given temperature according to the% of hygrometry, also allows to determine the qutés of energy necessary to dehumidify, increase or decrease the T ° of air .
How super nice I am (right?) I give you the diagram HERE
For the%, frankly, look on your azerty keyboard next to the enter key, you fear there .

hi and big thank you
I finally figured out how to know how much water is passing through my reactor
for the touches I fear and in addition they are full of sludge; I only clean the one that serves
I'll have to get a "new" keyboard, this one is more cleanable.
@ + and thanks again
