Simple Dilution

[mooreted]

I've been searching here and all over. All the formulas I find are way more complex than I need for this. And I'm probably over-thinking the whole thing.

The formulas I find assume you know how much volume of liquid you want, I don't care how much volume I end up with, only strength.

So, I have 20ml of 24mg/ml juice and I want to dilute it to 18mg/ml.

A simple formula would be handy.

id add 6ml of regular vg or pg.. anyone else?

or roughly thereabouts.

there are 5 "4ml" in 20ml and there 6 "4mg" in the 24 mg.. I think I just made up my formula. so I might be wrong lol. don't forget simple dilution will also dilute flavor. So actually you might want to add 3ml of regular pg or vg

Mathematically this relationship can be shown in the equation:

C1*V1=C2*V2

Where:
C1 = Concentration/molarity 1
V1 = Volume 1
C2 = Concentration/molarity 2
V2 = Volume 2

Therefore:

24*20=18x
---------------
480=18x
--------------
480/18=x
--------------
26.66=x

So, that doesn't work.

Oh, crap. I think I get it. I have 20ml if I dilute to 18 I will end up with 26ml so I would add approximately 6ml to end up at 26ml.

I think....

that was my non equipment using calculation too (not the beginning part, just the 6ml part.. why not start with 3ml?

 

[mooreted]

Could do that. Add 3ml, drip and see how it vapes and add more as needed.

Mostly I think my lungs are healing because the 24mg is too harsh now. I stepped on some other liquid with VG and it really smoothed it out.

 

[RandaPandaBear]

are your juices generally VG or PG based? because too much PG hurts my throat a bit, so I use VG mostly

 

[mooreted]

Well, vapor station doesn't say what the mix is. On the label it is has pg first then vg. I'm assuming it's probably 80/20. Just a wild guess though.

24-18=6. 6/24=.25 or 25%, you want a 25% reduction in nic sthrength.

20ml x .25 = 5ml, add 5ml to 20ml - not exact by volume but simple.

your 5ml addition is 0 nic

Percentages, of course. That's easy. Thanks.
