Question for those that know about ratios

[PressurePros]

John, both are correct and the difference is in the semantics of language. I have visited .edu sites, physics sites, mathmetician forums and the answers are just as diverse with convincing debate on both sides.

I can list hundreds of websites (.edu sites, mathematician forums, etc) as well as draw from my own education (which only went as far as number theory and advanced calculus before I switched from an engineering major) to support my viewpoint as it is in the context of this discussion. The more i read, the more I become thoroughly confused.

1. the relation between two similar magnitudes with respect to the number of times the first contains the second: the ratio of 5 to 2, written 5:2 or 5/2. 2. proportional relation; rate: the ratio between acceptances and rejections.

If this was not true ... than a 5GPM machine with a 1:5 injector could take 1 gallon chem and 5 gallon water to then be pumping out 6 gallons of liquid.... why wouldnt we just use the injector to suck up that extra gallon and turn our machines in 6GPM machines ?

Well, if you do not mind the low pressure that goes with the downstreamer, the yes you can get 6 gpm.

Keep it simple,whether it be ounces or gallons. If you have a 1:4 mix it is 5 total or whatever the numbers are. So in ounces it is 5 ounces total for chemical and water or for one gallon it is 160 ounces total with 128 for the water and 32 for the chem.

in dilution ratios it is not 1:4 .. 5 total ... DILUTIONS REPRESENT SOLUTE WITH IN SOLVENTS ... the total is 4 in a 1:4 .. most chem injectors are talked about at 20% draw rate .... this is 1/5 ... they are also said to be a 1:5 as a dilution ratio ... if we add 1 + 5 = 6 than 1/6 would be 16% draw rate. I do not know any typical 1:5 downstreamer that is a max 16% draw rate.... Dilution ratios compare the chemical to the total amount of solution its that simple. For those of you wanting to google and search up answers please refrain using ratio, fractions, proportions as keywords... look up dilutions because that is what we are doing to chemicals .. diluting them.

"... hundreds of sites..." Ken, you really need to get out more...

Here is a dilution ratio chart I found from a chemical company whom I would hope knows and has it right---but ya never know. It appears the ratio in chemical solutions "is" more of a fraction. 1:4 is 1/4 , according to this site
