let's work out how to actually dilute
this distillation to 40% alcohol by
volume now firstly we've got our
distillate here we need to actually find
out how strong it is now we use the
alcohol neither not the hydrometer used
for making the wash in the first place
okay so after pour a sample of the
distillate into this container where
we're going to use our alcohol meter to
see exactly what the alcohol by volume
level is of this particular wash we need
to know this is the first part of the
formula to work at how much water to put
into it okay so now what we're going to
do drop the alcohol meter into it now as
you can see here it comes to 85 percent
alcohol by volume all right all you want
it to come down to 40 so after we caught
this down is the first part of the sum
we're going to be actually doing we know
the volume of the liquid is one point
two five zero so now we can apply this
formula it's water into the
container but the formula is actual
alcohol by volume divided by required
alcohol by volume multiplied by the
liquid volume of what we'll just put
into the container
- the liquid volume and that equals how
much water we need to use to bring it
down to 40 percent alcohol by volume now
that was a bit confusing here's the
difference look at it in different
perspective eighty-five percent alcohol
by volume is the strength of that liquid
divided by 40 that's what we want to
bring it down to multiply it by the
volume of the quantity of liquid which
is one to five Oh take that one to five
over from it net gives us one point four
zeroes six liters of water that we need
to add to this to bring it down to forty
percent alcohol by volume okay so I've
got the water here drop it in the water
in and very shortly we'll be able to get
sampled this and do a test see what the
alcohol volume is it should be very well
close to 40% alcohol by volume now keep
in mind you've got water and alcohol
needs give it a bit of a mix up to make
sure that it's completely dispersed
properly and then what we're going to do
is we're going to take a sample you
don't need to you might find after a
Patrol an area
for doing this a few times you don't
need to actually do this as a final step
because you know it will be 40% alcohol
by volume alright so we've got our
content which is two point six five six
liters now we're going to take a sample
and we're going to see how strong this
particular final batch is as I said I
know it's going to be pretty well close
to spot-on 40% alcohol by volume but for
the sake of the exercise I'll go through
and show you here that it is 40% olive
oil so we drop the meter in there those
four bubbles by the way make sure those
around of the way bit does show this 40%
alcohol um-- now we have two point six
five six liters of alcohol that is ready
to go into the carbon filter ink
